The bioaccumulation and toxicity of heavy metals are serious threats to human activities and ecological health. The exploitation of environmentally friendly passivated materials is major importance for the remediation of heavy metal contaminated soil. This research developed a new type of environmental functional material with a core-shell structure, which is an iron-based material functionalized with phosphorus and carbon from sludge for heavy metal pollution remediation. The results indicated that the C/P@Fe exhibits excellent heavy metal removal ability, and the maximum removal rates of the two heavy metals in simulated wastewater could reach 100% under optimum reaction conditions. It also effectively converts the labile Cr/Pb into the stable fraction after 28 days of incubation, which increased the maximum residual fraction percentage of Cr and Pb by 32.43% and 160% in soil. Further analysis found that the carbon layer wrapped around the iron base could improve the electron transport efficiency of reducing iron, phosphorus and ferrum could react with heavy metal ions to form stable minerals, such as FeCr2O4, FeO·Cr2O3, Pb5(PO4)3OH, PbCO3, 2PbCO3·Pb(OH)2 and PbS, after reacting with C/P@Fe. The study demonstrated that the Iron-based materials functionalized with carbon and phosphorus from sludge provided a more efficient way to remove heavy metals. © 2024 Elsevier Ltd

The 3D flower-sphere UiO-66-NH2/Bi/BiOBr with good photocatalytic performance was successfully prepared by in-situ reduction and self-assembly process. The formation of semi-metal Bi was identified by XRD, XPS, HR-TEM and other methods. Transient photocurrent response and EIS spectra proved that compared with BiOBr nanosheets, the 3D flower-sphere structure, the reduction of metal Bi and the construction of Z-scheme heterojunction significantly improved the separation efficiency of photogenerated carriers in composite materials. The degradation rates of 50% UiO-66-NH2/Bi/BiOBr on tetracycline (30 mg/L TC) and norfloxacin (10 mg/L NOR) reached about 80% and 100%, respectively. Cycling experiments and XRD and XPS characterization results before and after the photocatalytic reaction verified that the composite had excellent reusability and stability. The experiment of free radical trapping agent and EPR spectrum analysis showed that in the UiO-66-NH2/Bi/BiOBr system, superoxide radical (·O2-) was the major active substance in the photocatalytic reaction, and Z-scheme degradation mechanism using metal Bi as electron conduction bridge was surmised. © 2021

The thermal stability of carbon-based catalysts remains a tremendous obstacle that deters their practical applications under high temperature range. Herein, a battery of MnCoOx supported hierarchical porous biochars with CeO2 encapsulation (MnCo/CeO2@BAC) were facilely fabricated for toluene catalytic oxidation. The strategy of CeO2 encapsulation can prevent biochars from high temperature damage and emerging hydrogen bonding with interfacial H2O, thereby strengthening the thermal stability and H2O resistance of such catalysts. The intrinsic relationship between their catalytic activities and physicochemical features was systematically comprehended via SEM, N2 adsorption-desorption, TEM, H2-TPR, XPS, XRD, O2-TPD and in situ DRIFT. 10%Mn0.5Co0.5/CeO2@BAC manifested joyful activity, outstanding mineralization rate, satisfactory thermal stability, preeminent SO2 and H2O toleration at a broad temperature interval. The impacts of O2, SO2 and H2O concentrations on toluene purification over 10%Mn0.5Co0.5/CeO2@BAC were delved, thereinto, SO2 and H2O exhibited prohibitive effects on toluene abatement, whereas O2 demonstrated stimulative influence on toluene elimination. In contrast to 10%Mn/CeO2@BAC and 10%Co/CeO2@BAC, 10%Mn0.5Co0.5/CeO2@BAC rendered superior catalytic performance benefitting from the cooperative effect of MnOx and CoOx, which contributed to improved redox property, more oxygen vacancies and lattice defects, higher proportions of Mn4+ and Co3+, larger Oads/Olatt ratio and better metal oxide dispersion. The possible reaction avenues and intermediates of toluene catalytic decomposition over 10%Mn0.5Co0.5/CeO2@BAC were also explored, among which chemically adsorbed oxygen dominated toluene adsorption and partial oxidation, while lattice oxygen was largely responsible for its deep oxidation. Ultimately, 10%Mn0.5Co0.5/CeO2@BAC showcased remarkable potential for industrial applications. © 2024, The Authors. All rights reserved.

Sulfamethoxazole (SMX) is a widely used antibiotic to treat bacterial infections prevalent among humans and animals. SMX undergoes several transformation pathways in living organisms and external environments. Therefore, the development of efficient remediation methods for treating SMX and its metabolites is needed. We fabricated a photo-Fenton catalyst using UIO-66 (Zr) metal-organic framework (MOF) dispersed in diatomite by a single-step solvothermal method for hydroxylation (HO-UIO-66). The HO-UIO-66-0/DE assisted Fenton process shows SMX degradation at 94.7% efficiency;however, HO-UIO-66 (Zr) is not stable. We improved the stability of the catalyst by introducing a calcination step. The calcination temperature is critical to improving the catalytic efficiency of the composite (for example, designated as HO-UIO-66/DE-300 to denote hydroxylated UIO-66 dispersed in diatomite calcined at 300 °C). The degradation of SMX by HO-UIO-66/DE-300 was 93.8% in 120 min with 4 mmol/L H2O2 at pH 3 under visible light radiation. The O1s XPS signatures signify the stability of the catalyst after repeated use for SMX degradation. The electron spin resonance spectral data suggests the role of h+, •OH, •O2-, and 1O2 in SMX degradation routes. The HO-UIO-66/DE-300 assisted Fenton process shows potential in degrading pharmaceutical products present in water and wastewater. © 2023, The Authors. All rights reserved.

H₂S selective catalytic oxidation has been considered as the most efficient method for the removal of residual H₂S in Claus tail gas. Carbon materials were regarded as a promising candidate for the reaction. However, its performance was rather poor. This study implemented an approach to enhance the catalytic performance of activated carbon catalysts through the synergy effect of rich defects and nitrogen species. The addition of phenanthroline, a nitrogen-containing compound increased the nitrogen content in the carbon framework, and annealing under an NH₃ atmosphere generated abundant surface defects. The pyridinic nitrogen species and defects facilitated the adsorption of H₂S. Moreover, the defects can also promote the generation of superoxide radicals, further resulting in the production of SO₂ and improving the catalytic performance through the Claus reaction. The best catalytic performance was achieved with the C-N-5 catalyst, and the sulfur yield was maintained higher than 95 % even at 220 °C. Furthermore, the oxygen-containing groups on the surface of carbon materials were the reactive oxygen species and the reaction obeyed the MvK mechanism, i.e., the adsorbed H₂S reacted with the oxygen-containing groups to form elemental sulfur, while the consumed oxygen-containing groups were regenerated by molecular oxygen. © 2025

In this study, a 3D marigold-like ZnIn2S4/Ti3C2 (MZ) Schottky junction was successfully fabricated by coupling 2D Ti3C2 nanosheets with hierarchical 3D ZnIn2S4 using a hydrothermal method. The introduction of Ti3C2 modulates the 3D marigold-like hierarchical architecture of ZnIn2S4, which not only boosted its photon capture performance and adsorption capacity caused by the increased specific surface area, but also effectively separated photo-generated electrons and holes via the well-defined 2D/2D interface between ZnIn2S4 and Ti3C2. Under visible light irradiation, the degradation performance of MZ composites on tetracycline (TC) and 7-Aminocephalosporanic acid (7-ACA) is significantly more robust than that of pristine ZnIn2S4 and Ti3C2. In particular, the degradation efficiency of TC (50 mg/L) and 7-ACA (25 mg/L) is 91% and 95% on the optimized MZ-6 composite within 120 min and 90 min, respectively. The synergistic effect of adsorption and photocatalytic degradation resulted in this high degradation efficiency. More importantly, MZ-6 still exhibits high photocatalytic activity and good physicochemical stability after many cycles. Meanwhile, residual ▪O2− and h+ played a major role in the degradation of TC and 7-ACA. This study could shed light for the construction of high-performing photocatalysts. © 2022, The Authors.

Coal gangue is a typical industrial waste, which will bring environmental challenges and resource depletion when piled up in large quantities, and heavy metal pollution is a prominent problem. In this study, Ca3(PO4)2 and calcium superphosphate fertilizer (CSF) were utilized to passivate coal gangue at different pollution levels, and its passivation mechanism was discussed. The results show that both Ca3(PO4)2 and CSF can effectively passivate coal gangue and effectively reduce moderate or high levels of coal gangue pollution to a slight or clean level. The passivation effect of CSF is slightly better than that of Ca3(PO4)2. Through characterization of coal gangue before and after passivation and simulation with Visual MINTEQ and PHREEQC software, it is found that Ca3(PO4)2 can provide PO3 2−, while CSF releases HPO3 –, which is ionized to generate more PO3 2−, and finally forms insoluble or slightly soluble phosphate with heavy metals. Leaching experiments show that the treated samples contain obviously more stable heavy metal components, and the leaching risk is lower than that of untreated coal gangue. In summary, this method proves its effectiveness in fixing heavy metals in coal gangue and provides an effective method for the harmless treatment of coal gangue. © 2025, Korean Society of Environmental Engineers.

Dear Editor,Tailed,double-stranded DNA(dsDNA)bacteriophages,which belong to the order of Caudovirales,have a tail attached to a pentameric vertex of the icosahedral capsid shell(head)through a 12-fold portal(Johnson and Chiu,2007).The phages package genomic dsDNA into a round procapsid using the portal in complex with an ATP-dependent terminase complex as the *** packaging,the procapsid shell expands to a more angular intermediate to match the size of the viral genome(Guo et al.,2014).When the phage head is full,the portal detects internal pressure and conveys a signal from the inner capsid to the exterior,which triggers a sequence of events-the terminase complex cleaving mature DNA genome from a multi-genome concatemer,the release of the terminase complex from the portal,and the attachment of the tail complex-in the completion of phage assembly(Lander et al.,2006;Johnson and Chiu,2007).At the beginning of phage infection,the tail is responsible for receptor recognition,and the portal and tail act as a tunnel for DNA delivery into the host cytoplasm(Johnson and Chiu,2007).These mechanisms of DNA packaging and ejection may also be conserved in many other DNA viruses,including herpesvirus(Wang et al.,2020;Yang et al.,2020).

The objective of this study was to compare the effects of nanoselenium (NS) and selenium yeast (SY) on the performance, egg selenium (Se) concentration, and anti-oxidative capacity of hens. A total of 216 Brown Hy-line hens (29-week old) were randomly allocated into three treatments (6 replicate/treatment, 12 hens/replicate). The pre-trial period lasted 7 days, and the experimental period lasted 35 days. Dietary treatments included corn-soybean meal basal diet (containing 0.16 μg Se/g, as control group), and basal diet supplemented with 0.3 mg Se/kg diet (Se was from NS or SY), called as SY group or NS group, respectively. At the end of the experiment, one hen per replicate from each treatment was slaughtered. Liver, spleen, and kidney tissues were sampled for the determination of Se concentrations. The results showed that NS or SY supplement significantly improved feed conversion ratio (P < 0.05), soft broken egg rate (P < 0.05), and the serum T-AOC value (P < 0.05) when compared with control group. Remarkably, the deposition of Se increased significantly (P < 0.05) and equivalently in egg, liver, and kidney of hens supplemented with both NS and SY. Interestingly, SY supplement also enhanced the serum CAT and SOD activities (P < 0.05), NS but not SY significantly reduced serum MDA (P < 0.05), whereas RT-PCR results did not show significant differences in the mRNA levels of antioxidant genes among three groups (P > 0.05). Taken together, dietary supplemented with SY or NS improved the Se deposition in eggs, liver and kidney of laying hens, increased antioxidant activity, and NS supplement had greater Se deposition in the kidney tissue than SY supplement. SY or NS supplement could be considered to be applied for Se-enriched egg production. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
