Summary: Eco-friendly, low-cost, and highly efficient noble metal-free rice husk biomass-derived biochar was developed as a cocatalyst to improve the performance of zinc indium sulfide for photocatalytic H2 production. The optimized nanocomposite exhibited superior H2 production compared to pristine zinc indium sulfide under simulated light irradiation. The enhanced activity was attributed to efficient interfacial contacts between the materials, high surface area and conductivity of biochar, and ultrathin-layered structure of the nanosheets.

Summary: Graphitic carbon nitride (CN) is a promising photocatalyst for environmental treatment. In this study, oxygen-doped CN nano sheets (CNO) with porous structures were synthesized using a self-assembled approach. The formation process of CNO and the control of oxygen doping amount were investigated. The obtained CNO photocatalysts showed excellent visible-light photocatalytic performances and the degradation pathway of sulfamerazine (SMR) was proposed. Density functional theory (DFT) calculations revealed that oxygen doping changed the electronic structure of CN, making it easier to activate O2. This work provides a novel approach for the development of high-performance nonmetal photocatalysts.

Summary: In this study, TiO2/SiO2 photocatalysts were prepared and the calcination temperature of 800 degrees C resulted in the highest photocatalytic activity for phenanthrene degradation. The composite material showed minimal phenanthrene uptake but strong photocatalytic activity, with the formation of Ti3+ under solar light irradiation promoting photoexcited electron trap and separation of electron-hole pairs. High electrophilic Fukui index atoms of phenanthrene were identified as the most reactive sites towards radicals during the degradation process.

Summary: The single-photon excitation can form 0D/2D heterojunctions that enhance photocatalytic activity by avoiding light shielding. However, it is challenging to prepare ultrasmall nanoparticles loaded on 2D nanosheets via one pot method. In this study, a Nb2O5/ZnIn2S4 (Nb-ZIS) heterojunction was fabricated through a solvothermal process assisted by Na2CO3 and thioacetamide (TAA), resulting in the growth of small Nb2O5 particles on ZnIn2S4 nanosheets. The interface between the 0D and 2D components reduces light blocking and promotes carrier separation. The Nb-ZIS heterojunction demonstrates significant improvement in H2 evolution and lignin degradation compared to other heterojunctions.

Summary: Regulating the second sphere of homogeneous molecular catalysts is an effective way to enhance their catalytic activities, but this has been rarely explored for heterogeneous single-atom catalysts due to synthetic challenges. However, in this study, an Au single-atom catalyst on amino-substituted graphdiyne (GDY) is constructed, where the amino group is located in the second sphere of the Au center. The presence of amino groups adjacent to Au atoms facilitates protonation and improves the catalytic performance for formic acid dehydrogenation.

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: Hydroxyl radical (center dot OH) and sulfate radical (SO4 center dot-) have been widely studied in advanced oxidation processes (AOPs) for organic pollutants degradation. In this study, a Co(II)/peroxymonosulfate activation system was established to degrade caffeine (CAF), and the different attack routes of SO4 center dot- and center dot OH were explored. It was found that SO4 center dot- is more likely to attack CAF kinetically, while only center dot OH can react via hydrogen atom abstraction (HAA) route. Radical adduct formation (RAF) is the most favorable route for both center dot OH and SO4 center dot- attack. These findings provide insights into the degradation mechanism of organic pollutants in AOPs driven by center dot OH and SO4 center dot-.

Summary: This study systematically investigated the changes in characteristics and composition of dissolved organic matter (DOM) under UV/PAA treatment, as well as the underlying mechanisms. UV/PAA treatment significantly reduced the aromaticity, apparent molecular weight, and fluorescent abundance of DOM, while producing more oxidized and saturated compounds. The reactive species (.OH and CH3C(O)O./CH3C(O)OO.) play a primary role in DOM changes, but with differences in reaction selectivity and mechanisms.

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: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
