Summary: Photocatalysis has attracted attention as a promising solution for energy shortage and environmental contamination. However, low light absorption and charge separation/transport efficiency limit the solar conversion efficiency. This study shows that the introduction of oxygen vacancies hinders charge separation/transfer in Ba2Bi1.4Ta0.6O6, while incorporating S extends the light absorption edge and improves charge separation/transport. As a result, S/Ov-Ba2Bi1.4Ta0.6O6 nanowires exhibit significantly higher photocatalytic activity for tetracycline hydrochloride degradation and hydrogen production.

Summary: This study compared the photocatalytic activities of active photocatalysts, including AgBr, ZnO, BiOI, and Cu2O, in the presence of a-MoO3. The results showed that a-MoO3 strongly inhibited the photocatalytic activity of TiO2, BiOI, Cu2O, and ZnO, but had no effect on AgBr. Therefore, a-MoO3 could be an effective inhibitor for evaluating newly explored photocatalysts.

Summary: The increasing demand for sustainable energy production has led to the development of efficient photocatalysts for water reduction to produce hydrogen. While polymeric carbon nitride (g-C3N4) has advantages such as low cost and thermal stability, a ternary composite of B-TiO2/MIL-53(Fe)/CN was fabricated for the first time to overcome its shortcomings and significantly improve photocatalytic activity for hydrogen evolution. This new composite shows enhanced charge carrier separation and transfer, leading to increased hydrogen production under visible and UV-visible light irradiations with the assistance of a co-catalyst.

Summary: In this study, we achieved remarkable piezo-photocatalytic activity over ultrathin Bi4O5I2 nanosheets and revealed the synergistic catalytic mechanism. We found that Bi4O5I2 has strong piezo-electricity through piezoelectric force microscopy (PFM) and COMSOL simulation analysis. The ultrathin nanosheets exhibited a piezo-photocatalytic efficiency for tetracycline hydrochloride (TH) degradation, which was 2.3-fold higher than the sum of single photocatalysis and piezocatalysis, and surpassed previously reported piezo-photocatalysts. Our in situ electrochemical and electron paramagnetic resonance (EPR) studies showed enhanced charge separation and transfer, as well as reactive species evolution (superoxide radicals and holes) in the piezo-photocatalytic reaction process, attributed to the piezoelectric field and band bending. This work highlights the impact of the piezoelectric field on enhancing photocatalytic performance and advancing our understanding of the synergistic piezo-photocatalytic mechanism.

Summary: Metal-semiconductor hybrid photocatalysts, especially those decorated with non-noble metal like copper, have attracted great attention for their potential in solar-to-hydrogen evolution. In this study, copper particles were successfully deposited on the surface of calcium titanate nanorods through a simple solvothermal method. The resulting CaTiO3/Cu composites exhibited enhanced solar-to-hydrogen performance, with the optimized Cu loading amount achieving a hydrogen evolution rate much higher than bare CaTiO3. The efficient separation of photogenerated charges between the CaTiO3 nanorod and Cu nanoparticles was proposed as the reason for the enhanced water splitting and H2 production. This work further confirms the effectiveness of metallic Cu decoration in promoting the photocatalytic performance of semiconductor photocatalysts for H2 production.

Summary: In this study, it was discovered that trace Mn(II) can effectively catalyze the oxidation of organic contaminants by periodate (PI), outperforming the representative TRSs-dominated AOPs. The formation of colloidal MnO2 was found to be responsible for the enhanced treatment performance, serving as both oxidant and catalyst. The study elucidated the roles of Mn(II) and colloidal MnO2 in PI-mediated contaminant degradation, highlighting the superiority of trace catalyst-assisted process without TRSs involvement in maximizing oxidation efficiency and avoiding undesired side reactions.

Summary: Chinese loess on the Loess Plateau provides valuable records of paleoclimate changes. By analyzing the grain-size components of aeolian sediments, we reconstructed the history of the East Asian winter monsoon (EAWM). Our study found that two major grain-size components (fine and coarse) varied among different loess sections due to factors such as material source distance and post-depositional pedogenesis. Comparisons between sensitive grain-size components and EAWM patterns indicated that the coarse grain-size components can serve as a proxy indicator for the EAWM on the Loess Plateau.

Summary: FT -x composites with a core-shell structure were fabricated by a hydrothermal method, using MIL-125(Ti) as a sacrificial template. The unique structure and synergy between FeS2 and TiO2 greatly improved the photo-Fenton activity and stability of FT-1. Under UV light irradiation, the catalytic activity of FT-1 was boosted and the reactivity decline was prevented through the generation of photogenerated electrons and .OH. Additionally, FT-1 displayed excellent photo-Fenton activity in a wide pH range and good anti-interfering ability.

Summary: Electrochemical disinfection (ED) effectively removes antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in wastewater treatment. This study investigated the disinfection mechanism at a microcosmic level using different strains of Escherichia coli (E. coli) with varying antibiotic resistant phenotypes. Findings showed that bacteria with multiple antibiotic resistance had higher viability during disinfection compared to those with fewer resistance. Notably, antibiotic-resistant phenotypes remained largely unchanged during disinfection, while genotypes closely responded to E. coli's resistance. β-lactamase resistance genes played a significant role in cross-resistance between antibiotics and electrochemical oxidation by strengthening the cell wall and membrane. This study provides important insights into and control of antibiotic resistance with advanced oxidation processes.

Summary: Interfacial modulation of catalysts can enhance catalytic activity, and this study focuses on revealing the mechanism of reactive species production at different interfaces. Zr-S-4 active sites were successfully constructed on ZnIn2S4 nanosheets, effectively modulating the reaction interface and band structure, which significantly boosted the photocatalytic activity. The modified catalyst exhibited a 3-fold increase in the kinetic rate constant for photocatalytic degradation compared with the pristine ZnIn2S4, and the degradation pathway of TC was altered due to the regulation of reactive species.

Summary: Rationally regulating reaction mechanisms in Fenton-like reactions by tuning the properties of catalysts is challenging but significant. Various catalysts with different active center sizes were synthesized to realize the switching of reaction mechanisms and pollutant degradation routes in peroxymonosulfate (PMS) activation systems. The transformation of reaction mechanism from radical oxidation to nonradical oxidation was observed with the decrease of active center size. The toxicity tests indicated that the conversion from non-selective to selective oxidation resulted in lower toxicity of effluent after reaction, reducing environmental risks.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
