Summary: A novel Z-scheme CdS/CeO2/g-C3N4 nanocomposite was synthesized by a solvothermal method and its photocatalytic activity for the degradation of phenol was evaluated. The nanocomposite exhibited remarkable photocatalytic activity with a degradation rate of 95 % in 180 min, surpassing that of pure CeO2 and CdS/CeO2. The enhanced photocatalytic ability is mainly attributed to the higher adsorption capacity of three-dimensional porous g-C3N4 and the three-dimensional space electric field formed by its complex with CdS and CeO2.

Summary: In this study, cobalt boride (Co2B) nanosheets with ordered short-range amorphous phases but disordered long-range structure were synthesized and coupled with graphic carbon nitride (CN) photocatalysts through an in-situ chemical reduction method. The optimized Co2B/CN nanohybrids showed a H2 evolution rate of 56.86 mu mol/h with the highest AQY of 22.8%, outperforming Pt decorated CN. The disordered structure of Co2B nanosheets provided abundant active sites, while the metallic nature of Co2B facilitated electron transfer and inhibited electron-hole recombination.

Summary: The study compared the adsorption behaviors of methylene blue on microalga residue powder (MRP) and biochars derived from microalga residue (MRB) produced at different pyrolytic temperatures. Different models were used to describe the adsorption processes, and it was found that MRP showed better adsorption ability compared to MRB due to the loss of oxygen-containing functional groups after pyrolysis. Overall, microalga residue performed better for methylene blue removal compared to their pyrolyzed analogs.

Summary: Zero valent iron coupled with bioreactors is a promising technology for mitigating antibiotic resistance genes (ARGs), with the potential to reduce ARGs propagation by inhibiting quorum sensing (QS) systems. The addition of ZVI in anaerobic bioreactors fed with oxytetracycline significantly decreased the total absolute abundance of tet ARGs, suggesting a potential mechanism of reduced ARGs transfer through inhibition of QS systems.

Summary: Microplastics have been frequently found in freshwater environments, raising concerns about their ecological effects, particularly the impact of biofilms on freshwater ecosystems. The colonization of microbes on microplastics alters their transport behavior, with biofouled microplastics showing increased sinking tendencies compared to pristine ones. This highlights the importance of studying how biofouling affects the sinking and distribution of microplastics in freshwater environments.

Summary: This study proposed a new modification idea and synthesized a high-efficiency plant-based flocculant through three rounds of reactions using tannin, formaldehyde, and ammonia chloride. By employing three rounds of Mannich reactions, a modified tannin with a larger molecular weight and complex structure was obtained. The flocculation tests showed that the flocculation capacity of the modified tannins increased with the number of reaction rounds, reactants ratio, and appropriate reaction time and pH. The new modification idea and high-efficiency modified tannin are significant for the development of environmentally friendly flocculants and addressing the drawbacks of traditional chemical flocculants.

Summary: This study investigates the performance of sulfidated nanoscale zero-valent iron (S-nZVI) in removing pentachlorophenol (PCP) from water. The results show that PCP removal is achieved through a combination of adsorption, dechlorination, and OH-mediated oxidation, with dechlorination playing a leading role. The amount of adsorbed PCP correlates well with the dechlorination rate constant, although this correlation is not observed under certain water chemistry conditions. The effects of solution chemistry, such as pH, anions, organic matter, and oxygen conditions, on PCP adsorption and transformation are also studied.
