Roxarsone (ROX) is the main form of As pollution in the world, and developing effective methods for its elimination is beneficial to human health and ecological environment. Herein, we report glutaraldehyde-crosslinked chitosan encapsulated CoCe-LDH as an outstanding catalyst for the advanced oxidation of ROX and the efficient adsorption of inorganic arsenic. 100% of ROX and more than 98.5% of As(III)/As(V) were eliminated, and over 99.3% of remained inorganic arsenic was oxidized to low toxicity As(V) in the PMS-activation system, and some specific properties of LDH are considered the main reasons. The hierarchical anion exchange has been confirmed to be beneficial for constructing a high concentration PMS inter layer microenvironment. And the unique reverse electron transfer process induced the 100% selective production of singlet oxygen. This work not only develops an advanced ROX removal method, but also provides a new understanding of LDH-based advanced oxidation process. © 2024, The Authors. All rights reserved.

Photocatalytic H2 production with selective oxidation of organic moieties in an aqueous medium is a fascinating research area. However, the rational design of photocatalysts and their photocatalytic performance are still inadequate. In this work, we efficiently synthesized the MoS2 tipped CdS nanowires (NWs) photocatalyst using soft templates via the two-step hydrothermal method for efficient H2 production with selective oxidation of benzyl alcohol (BO) under visible light illumination. The optimized MoS2 tipped CdS NWs (20% MoS2) photocatalyst exhibits the highest photocatalytic H2 production efficiency of 13.55 mmol g-1 h-1 with 99% selective oxidation of BO, which was 42.34 and 2.21 times greater photocatalytic performance than that of pristine CdS NWs and MoS2/CdS NWs, respectively. The directional loading of MoS2 at the tips of CdS NWs (as compared to nondirectional MoS2 at CdS NWs) is the key factor towards superior H2 production with 99% selective oxidation of BO and has an inhibitory effect on the photo corrosion of pristine CdS NWs. Therefore, the amazing enhancement in the photocatalytic performance and selectivity of optimized MoS2 tipped CdS NWs (20% MoS2) photocatalyst is due to the spatial separation of their photoexcited charge carriers through the Schottky junction. Moreover, the unique structure of MoS2 flower at the tip of 1D CdS NWs offers separate active sites for adsorption and surface reactions such as H2 production at the MoS2 flower (confirmed by Pt photo deposition) and subsequently the selective oxidation of BO at the stem of CdS NWs. This rational design of a photocatalyst could be an inspiring work for the further development of efficient photocatalytic system for H2 production with selective oxidation of BO (a strategy of mash two potatoes with one fork). © 2024, The Authors.

Nowadays, saline wastewater is regarded as a challenge to wastewater treatment plants, in which high salinity shows an unfavorable effect on the conventional biological technology. Aerobic granular sludge (AGS) has attracted interests as a promising technologies for saline wastewater treatment because of its compact structure and the ability to withstand toxic loadings. Therefore, this study investigated salt-tolerance performance and mechanisms of AGS under low-salinity and high-salinity conditions that the saline concentration ranged from 0 to 50 gNaCl/L. The results showed that AGS could withstand long-term saline stresses, and the maximum salinity reached 50 g/L within 113 d. Under 10 g/L, 30 g/L and 50 g/L salinity, COD removal were 90.3%, 88.0% and 78.0% respectively, which suggests effective organic matter removal could reach in aerobic granular system. AGS remained relatively high bioactivity under 10 g/L and 30 g/L salinity. AGS also maintained strength and aggregation under 10 g/L and 30 g/L salinity. The integrity coefficients (IC) maintained 96.2% and 97.7%. The relative hydrophobicity (RH) remained 80.5% and 83.8% at the same time. The salt-tolerance mechanisms should be ascribed to overproduction of extracellular polymeric substances (EPS) by non-halophilic bacteria that enhanced sludge aggregation. And the compact structure that ensure the microorganisms bioactivity within AGS maintained the function of removing organic matters under 10 g/L and 30 g/L salinity. Under 50 g/L salinity, major shift of microbial community happened. Moderately halophilic bacteria, including Salinicola, Thioclava , Idiomarina and Albirhodobacter , prevailed in the reactor. The salt-tolerance mechanisms under 50 g/L saline condition were that the dominated microbial communities shifted to moderately halophilic bacteria, which could maintain aerobic granular stabilization and organic matters removal. These results provide further insight into the application of AGS for saline

Exploiting metal chalcogenide-based photocatalysts has fascinated researchers as a source of green hydrogen (H2) energy. Herein, we have designed a novel selenium-enriched NiSe1+x/ZIS (NiSexZ) photocatalytic system via a two-step hydrothermal and facile photo-deposition method. It was fascinating to conclude here that the NiSexZ photocatalytic system showed boosted H2 evolution results in comparison with other sulphur-enriched NiS1+x/ZIS (NiSxZ) and tellurium-enriched NiTe1+x/ZIS (NiTexZ). The optimized NiSe0.5Z composite exhibited a photocatalytic H2 evolution of 3.24 mmol g -1 h -1, a 9.8-fold increase over pure ZIS and it demonstrated an apparent quantum efficiency (AQE) of 2.06% via 420nm filter. Moreover, sulphur (S), selenium (Se), and tellurium (Te) synergistic active sites were exposed to promote H2 evolution reaction in this work. Given the significant advancements and commendable performance exhibited by the Se-Hads across the week bond, it is extremely probable that the NiSe1+x cocatalyst holds immense potential for the development of sophisticated photocatalytic materials. © 2024, The Authors.

Selective methanol oxidation reaction (MOR) to value-added formate can maximize the input energy utilization for water electrolysis by replacing the high onset-potential and kinetics sluggish oxygen evolution reaction. However, to date only first-row 3d transition metal oxides present the capacity of selective MOR, motivating the design of new kinds of electrocatalysts to further enhance the MOR performance. Herein, we show amorphous Nb2O5 as an efficient electrocatalyst, for the oxidation of methanol to formate, with a low operating potential of 1.47 V vs. RHE to achieve industry-relevant current densities (>100 mA cm-2) with a Faraday efficiency of ~100%. We demonstrate, via operando Raman measurements, this superior electrochemical MOR activity originated from the in-situ induced short Nb-O bonds from the amorphous structure, while the crystalline Nb2O5 fails to generate this active site resulting in a poor activity. This work may provide valuable insight for developing novel transition metal oxides for MOR catalysts. © 2023, The Authors. All rights reserved.

Nanoplastics (NPs) can be absorbed by crop roots and translocated to shoots, but whether the process follows a unidirectional pathway in different plant species remains unclear. This study investigated the translocation and accumulation of europium-labeled polystyrene NPs in cucumber (dicot) and maize (monocot) seedlings using a split-root system. The results showed that NP accumulation was highest in exposed roots (E-R), followed by unexposed roots (UE-R), and then shoots in both plants. In cucumber, NP accumulation in E-R was 26.84 % higher than in maize; while in maize, the translocation factor from shoot to UE-R was 4.45 times greater than in cucumber. TEM images confirmed NP transport from root to shoot via xylem, while confocal images showed the redistribution of NPs from shoot to root via phloem. AgNO treatment (5-50 μmol L) revealed aquaporin-mediated regulation of NP accumulation, with concentration-dependent increases of 30.37-220.7 % in cucumber roots and 36.38-53.65 % in maize shoots. Transcriptomic analysis revealed that NP accumulation interacted with aquaporin gene expression, where differential regulation of tonoplast intrinsic, plasma membrane intrinsic, and nodulin 26-like intrinsic proteins drove translocation differences. This study offers critical insights into the "root-to-shoot-to-root" translocation of NPs, informing crop safety assessments amid global plastic pollution.

Converting methanol to high-value formate through electrochemical methods can significantly reduce the energy consumption associated with conventional production processes. In this study, we directly synthesized iron-doped cobalt phosphate (Fe-CoPO) on nickel foam (NF) to achieve excellent activity for the methanol electro-oxidation reaction (MOR). Our results demonstrated that Fe-CoPO produced a current density of 100 mA·cm−2 at a significantly low operating potential of 1.436 V (vs. reversible hydrogen electrode (RHE)) and operated steadily for 16 h at this current density with a Faradaic efficiency (FE) of 97%. Furthermore, Fe-CoPO maintained a high FE of 100% even at an extremely high current density of 300 mA·cm−2 for 8 h. We found that the high MOR activity of Fe-CoPO results from electrochemical reconstruction to generate the Co2+/3+–O bond. The heterogeneous interface between Fe and Co inhibits the formation of Co4+, which significantly enhances the MOR activity. Thus, this work not only provides insights into the mechanism of MOR over Co-based catalysts but also offers a novel direction for developing highly active MOR catalysts. © The Author(s) 2025.
