In heterogeneous catalytic systems, catalyst activation induced by reactants or products, often attributed to surface restructuring, represents a compelling phenomenon. The catalytic nature and reaction mechanism of the molybdenum nitride system in the reverse water-gas shift reaction (RWGS) remain subjects of ongoing debate, with no consensus reached to date. In this work, we demonstrate that γ-Mo2N can be effectively activated via in situ treatment under the RWGS reaction atmosphere at 500 °C, leading to a significant enhancement of its catalytic activity. A deep investigation revealed that surface restructuring is the underlying mechanism responsible for the activation of γ-Mo2N. During the RWGS process, Mo6+ species on the surface of γ-Mo2N are converted into Mo4+ under the induction of the reaction atmosphere, thereby enhancing the activation of H2 and improving the catalytic activity. Notably, the surface restructuring effect enables γ-Mo2N to achieve catalytic activity and stability comparable to those of metal-based catalysts reported in the literature. This work provides significant insight into the real active site and the pivotal role of γ-Mo2N in RWGS reactions. © 2025 American Chemical Society.

Inorganic pigments, which often contain significant amounts of nanoparticles, are crucial chemicals for human life. They are produced in massive quantities and widely used in consumer products, food, and pharmaceuticals. Herein, we reported that a variety of commonly used commercial inorganic pigments possess peroxidase-like activity, catalyzing hydrogen peroxide (H2O2) decomposition into reactive oxygen species, primarily hydroxyl radical ([rad]OH) and superoxide radical anion (O2[rad]−). The catalytic activity of inorganic pigments exhibits saturation kinetics as described by the Michaelis-Menten model, with optimal pH and temperature conditions that can be found in the human body. The enzyme-mimicking activity is strongly correlated with the formation of [rad]OH (R2 = 0.98), indicating the radical-mediated reaction pathway. The peroxidase-like activity of inorganic pigments can induce significant oxidative stress at health-relevant H2O2 concentrations (3–30 μM), as demonstrated by the ascorbic acid assay. Additionally, the peroxidase-like activity of inorganic pigments is able to mediate the oxidation of tetracycline, with oxidation rate constants positively correlated with the pigments' peroxidase-like activity. The discovery of peroxidase-like activity of commercial inorganic pigments sheds light on the reported oxidative stress exerted by these pigments and has important implications for the health risk assessment of inorganic food and pharmaceutical colorants, as well as colored consumer products. © 2024 Elsevier B.V.

Agricultural soil is related to food security and human health, antibiotics and heavy metals (HMs), as two typical pollutants, possess a high coexistence rate in the environmental medium, which is extremely prone to inducing antibiotic-HMs combined pollution. Recently, frequent human activities have led to more prominent antibiotics-HMs combined contamination in agricultural soils, especially the production and spread of antibiotic resistance genes (ARGs), heavy metal resistance genes (MRGs), antibiotic resistant bacteria (ARB), and antibiotics-HMs complexes (AMCs), which seriously threaten soil ecology and human health. This review describes the main sources (Intrinsic and manmade sources), composite mechanisms (co-selective resistance, oxidative stress, and Joint toxicity mechanism), environmental fate and the potential risks (soil ecological and human health risks) of antibiotics and HMs in agricultural soils. Finally, the current effective source blocking, transmission control, and attenuation strategies are classified for discussion, such as the application of additives and barrier materials, as well as plant and animal remediation and bioremediation, etc., pointing out that future research should focus on the whole chain process of "source-process-terminal", intending to provide a theoretical basis and decision-making reference for future research. © 2024 Institute of Process Engineering, Chinese Academy of Sciences

Environmental pollution 2025年 375卷 126376页

The introduction of rare earth elements (REEs) and precious metals (PMs) containing wastes in aged landfills leads to a significant pollutant and resource potential. Against this backdrop, the accumulation of REEs and PMs in soil-like-fractions (SLF) remains uncertain. This study pioneers a comprehensive analysis of the REE/PM speciation, ecological risks of REEs and economic potential of PMs in SLF. Concentrations of REEs and PMs varied from 146.14 to 464.28 mg/kg and 4.20–111.86 mg/kg, respectively, with a particular enrichment in the upper SLF. REEs and PMs were immobilized by SLF and stabilized into organic- and mineral-bound fractions. A dataset linking urban development and landfill conditions to REE/PM concentrations was created, and the Support Vector Regression (SVR) model was utilized to achieve high-precision prediction of REEs and PMs content (R2 > 0.9). The Shapley Additive Explanations (SHAP) algorithm revealed development of electronics industry as the primary driver of REE/PM enrichment, followed by organic matter content in SLF. The potential ecological risk index (PERI) showed limited risks of REEs, but the bioavailable REEs posed long-term accumulation and chronic toxicity in terrestrial organisms, emphasizing the detoxification before SLF reusage. The economic potential of PMs reached 871.82 USD per ton of SLF, higher than primary minerals. These findings provide new insights into valuable resources during landfill mining and suggest potential areas for applying modern techniques, such as machine learning, to landfill management. © 2025 Elsevier Ltd

Biopolymers with different biodegradability result in the asynchronous production of humus precursors during anaerobic digestate composting, which hinders humus formation. This study aimed to improve the humification process of digestate composting with Humus Soil Biomaterial (HSB) as ameliorant, and unveiled corresponding humification mechanisms. Results indicated that HSB containing pumice stone, phenolics, and native microbes promoted the humification process of digestate composting and contributed to higher aromaticity and humification degree. HSB provided additional phenolics as aromatic skeleton to polymerize with amine-N to rapidly form humic substances, which avoided the adverse effects of lignin rate-limiting decomposition on humification process while reducing mineralization of amine-N precursors. Pumice stone and native microbes in HSB improved microbial composition by increasing microbial abundance and diversity, respectively, which strengthened the interactions between microorganisms and organics to accelerate humus formation and composting maturity. This study proposed a novel rapid humification option for the resourceful treatment of anaerobic digestate. © 2025

The simultaneous partial nitrification, anammox, and denitrification (SNAD) process is widely applied for treating high-ammonia wastewater, but its application to low-ammonia organic wastewater has been scarcely explored. In this study, a partial nitrification and denitrification coupled with simultaneous partial nitrification, anammox, and denitrification (PND-SNAD) system was established to treat organic wastewater with low ammonia concentration. Experimental results revealed that sulfide at 5 mg/L selectively inhibited nitrite-oxidizing bacteria (NOB) but had little effect on ammonium-oxidizing bacteria (AOB). Finally, NOB was suppressed in PND system by intermittently adding sulfide to the PND system. The PND system provided nitrite and activated sludge enriched with AOB to the SNAD system during stable operation. The SNAD system demonstrated chemical oxygen demand (COD) and nitrogen removal efficiencies of 89.86 % and 86.45 %. Candidatus Brocadia and Nitrosomonas were the main ammonium oxidizing bacteria (AnAOB) and AOB. The contribution of AOB and denitrifying bacteria (DNB) to nitrogen transformation was 67.15 % and 25.33 % in the PND system. In the SNAD system, the contributions of AnAOB, AOB, and DNB were 34.40 %, 33.59 %, and 27.56 %, respectively. Overall, this study provided a new sustainable strategy for treating organic wastewater with low ammonia concentration. © 2025 Elsevier Inc.

Enhancing the catalytic activity of aluminum oxide for permanganate oxidation of phenols by N-doping and hydration

引用

Applied Catalysis B: Environmental 2025年 374卷

作者： Wei, Junyan Zhang, Shengnan Liu, Boying Wei, Zhongbo Wang, Zunyao Tang, Kai Andersen, Henrik Rasmus Qu, Ruijuan State Key Laboratory of Pollution Control and Resources Reuse School of the Environment Nanjing University Jiangsu Nanjing210023 China Department of Environmental and Resource Engineering Technical University of Denmark Lyngby2800 Kgs Denmark

Aluminum oxide is an excellent catalyst in organic synthesis and petrochemistry but requires good crystallinity. This study used a simple low-temperature pyrolysis method to successfully synthesize an amorphous N-doped aluminum oxide (N-AOam, N-[Al(OH)3]0.47[Al2O3]0.53) sample for catalytic KMnO4 oxidation. N-AOam reduced the activation energy of the reaction and increased the TOC removal by forming oligomers. From a combined analysis of probe test, electrochemical measurement and DFT calculations, it was revealed that both N doping and hydration could lead to a decrease in LUMO energy of the MnO4−···AO complex, facilitating the electron transfer process to enhance the oxidizing capacity of KMnO4. Finally, the universality of the KMnO4/N-AOam system for catalytic oxidation of various phenols was verified, with the establishment of a QSAR model by multiple linear regression and machine learning optimization. This study fundamentally reveals the key role of nitrogen doping on the basic catalyst alumina, helping the green and low-cost traditional oxidant KMnO4 to be rebirthed. © 2025 Elsevier B.V.

A pilot-scale study on performance and deactivation mechanism of MnOx supported on Y zeolite for ozone catalytic oxidation of VOCs at low temperature

引用

Chemical Engineering Research and Design 2025年 218卷 421-427页

作者： Shao, Qi Xiao, Haoran Gao, Lei Chen, Huiming Long, Chao State Key Laboratory of Pollution Control and Resource Reuse School of the Environment Nanjing University 163 Xianlin Avenue Nanjing210023 China Nanjing University & Yancheng Academy of Environmental Protection Technology and Engineering Yancheng224000 China

As a VOCs elimination method at low temperature, ozone catalytic oxidation technology has received extensive attention recently. However, there is still lack of reports on the pilot-scale application of this technology. Herein, a pilot-scale catalyst (Mn/Y) was prepared by loading MnOx on the commercial Y zeolite using a simple impregnation method, which exhibited effective removal effect of TVOCs in the actual VOCs exhaust gas from a shoe factory. Although Mn/Y was inevitably deactivated during the long-term reaction, the catalytic activity of the catalyst can be restored after in-situ heating in the ozone flow. Through the investigation of the physical and chemical structural properties of the fresh catalyst, deactivated catalyst and regenerated catalysts, it was found that the disappearance of some easily reducible MnOx and ozone decomposition site, as well as the accumulation of some by-products were the reason for the deactivation of the catalyst. This work can provide some theoretical guidance for the ozone catalytic oxidation of VOCs from a pilot-scale view. © 2025 Institution of Chemical Engineers

Compound dry-hot extremes (CDH) cause devastating socio-economic impacts on society and ecosystems. Univariate risk assessment might not catch the potential impacts of CDH. Considering the negative correlation of average summer temperature and precipitation, this study developed two kinds of copula-based likelihood multiplication index, such as the whole likelihood multiplication index () and the second likelihood multiplication index (), to enumerate the attribution and projection of compound dry-hot events in Yellow River Basin (YRB) of China. Observed datasets show that the areas influenced by the CDH within YRB are increasing, and the most-extreme CDH event was observed several decades ago. Comparison of natural-only and all forcing-based CMIP6 data show that anthropogenic factors are causing the increasing trend of affected areas. Results of analysis showed that changes in the risk of CDH events could depend on not only the temporal variation of the marginal distribution but also the change in the dependence structure between variables. By comparing the difference between and, all grid-based areas in YRB were classified into five cases of combined effects which would help identify the synergistic and non-synergistic contribution of variations in marginal distribution and dependence structure of variables on risk of CDH events. Under Shared Socioeconomic Pathways scenarios (SSPs), the likelihood of concurrent dry-hot extremes is expected to increase in more than half of YRB while small parts of YRB would also experience decreasing likelihood of CDH events with 38.2% of grids under SSP1-2.6, 37.4% under SSP3-7.0 and 36.9% under SSP5-8.5 belonging to case 3 and 6. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.
