Summary: In this study, a visible light responsive Z-scheme AgI/Ag/AgVO3 hybrid nanorods were successfully prepared and showed enhanced catalytic activity and stability in environmental remediation. Compared with traditional AgVO3 and Ag/AgVO3, the absorbance of the hybrid nanorods in the visible light region was significantly improved, leading to higher degradation efficiency. The trapping experiments confirmed that the degradation of AO-II was mainly attributed to h(+) and center dot O-2(-). The efficient photocatalytic activity can be explained by Z-type mechanism, promoting the effective separation of photogenerated charges.

Summary: This study designed a novel photocatalyst GO/alpha-AgVO3 to improve the separation of photocarriers and enhance the catalytic performance. The 0.5 wt% GO/alpha-AgVO3 exhibited the best performance for RhB decomposition under visible-light irradiation. The enhanced performance was attributed to the suitable bandgap of alpha-AgVO3 nanorods and the efficient separation of photocarriers by GO nanosheets.

Summary: A floating photocatalyst was successfully constructed by loading a specific nanocomposite onto a modified polyurethane sponge, which achieved high removal efficiency of Microcystis aeruginosa under visible light. The catalyst could be reused and its performance was influenced by loading content of nanoparticles, algae density, and concentration of natural organic matters. The physiological characteristics of algae cells were severely affected during the photocatalytic process, leading to their death. The study proposed a possible photocatalytic inactivation mechanism of algae cells.

Summary: Novel zinc peroxide/carbon quantum dots (ZnO2/CQD) composites were synthesized using an in-situ composite process. The composites exhibited superior visible-light photocatalytic performance for tetracycline degradation and Escherichia coli inactivation. Superoxide radicals and singlet oxygen were identified as the main reactive oxygen species responsible for these processes. The introduction of carbon quantum dots reduced particle size, increased specific surface area, and promoted visible-light absorption and separation of photogenerated electron-hole pairs, leading to enhanced photocatalytic performance.

Summary: A novel ternary AgI/ZnIn2S4/BiVO4 composite photocatalyst (AZB) was successfully prepared and characterized. The photocatalytic activity of AZB was evaluated for tetracycline degradation, showing a high degradation rate of 91.44% within 150 min. The AZB heterojunction exhibited outstanding performance, with reaction rate constants 4.68, 3.27, and 3.27 times higher than that of pure BiVO4, AgI, and ZnIn2S4 respectively. Active species trapping experiments and ESR analysis supported the proposed dual Z-Scheme pathways for efficient charge separation. This research provides insights for the design of ternary dual Z-scheme heterojunctions with enhanced photo-absorption, charge separation, and photodegradation for environmental remediation.

Summary: CdS/Ti3C2/g-C3N4NS Z-scheme composites were prepared and showed enhanced visible light photocatalytic activity compared to Ti3C2/g-C3N4NS and CdS alone, with the degradation capacity for orange II approximately 3.2 and 10.7 times higher, respectively. The use of Ti3C2 as an electron transfer medium in the heterostructure led to improved separation ability of photoinduced e(-)-h(+) pairs, thereby enhancing visible light-driven photocatalytic activity. This study provides new insights for constructing high efficiency Z-scheme heterostructure photocatalysts.

Summary: A facile three-step photo-deposition method was applied to synthesize Ag and AgI modified ZnO composites, enhancing the photocatalytic efficiency of Naproxen degradation under visible-light irradiation. Different initial pH, NO3-, and SO42- had little impact, while Cl- accelerated the degradation rate. O2- and h+ played significant roles, and cycling experiments showed a decrease in removal rate after the initial run but stability in subsequent reactions.

Summary: Replicating the enzymatic surface microenvironment in vitro is challenging, but constructing an analogous model could facilitate our understanding of surface effects and aid in developing an efficient bioinspired catalytic system. In this study, five unique Cu2O morphologies were generated, and the surface morphology variations were found to be a consequence of differences in the exposure of low-index facets. The reactivity of Cu2O was found to be influenced by the proportion of {110} planes, with r-Cu2O exhibiting the highest reactivity.

Summary: This article reports a transition-metal-free process for in situ denitrogenation of tosylhydrazones, resulting in the production of various sulfones. The authors used a phenalenyl-based odd alternant hydrocarbon as a photoredox catalyst, which acted as a potent oxidant to facilitate the denitrogenation reaction. The method showed wide functional-group tolerance and high yields, making it suitable for late-stage modification of natural products.
