Summary: SnO2-x nanocrystals were prepared by controlling the proportions of Sn4+/Sn2+ precursors using a simple hydrothermal method. The Sn2+ doping introduced oxygen vacancies into the SnO2 nanocrystals, with their concentration controlled by the amount of Sn2+ doping. Structural characteristics of SnO2-x nanocrystals were analyzed through various techniques, revealing that higher Sn2+ concentration led to more structural disorder and changes in electronic structure. This resulted in improved visible light absorption and excellent photocatalytic activity.

Summary: SnO2:Bi3+ nanoparticles were synthesized by a one-step hydrothermal method. The influence of Bi3+ impurity concentrations on the size, morphology, and band gap width of SnO2:Bi3+ materials was deeply investigated. The interaction between the SnO2 crystalline host and Bi3+ was studied using characterization techniques such as SEM, XRD, UV-Vis, PL, and EPR. The photocatalytic activity of the SnO2:Bi3+ nanoparticles was higher than that of pure SnO2 nanoparticles. The high degradation efficiency of the SnO2:Bi3+-2% sample was attributed to its small crystal size and defect states, which increased the specific surface area and surface charge carrier transfer rate.

Summary: In this study, an O-g-C3N4 (OCN) and SnO2 (SO) coupled photocatalyst was synthesized and evaluated for the degradation of RhB and reduction of Cr(IV) under simulated sunlight irradiation. The 30-SO/OCN nanocomposites exhibited higher catalytic activity than 30-SO/CN nanocomposites, attributed to the special surface of OCN and the formation of a heterojunction between SO and OCN.

Summary: A novel Ag@Bi5O7I/Bi(OH)3 heterojunction with enhanced photocatalytic antibacterial activity against Escherichia coli (E. coli) under visible light excitation was prepared. The photocatalytic antibacterial mechanism was confirmed through SEM, live/dead cell staining, and SDS-PAGE assay. The improvement of photocatalytic activity can be mainly attributed to the construction of heterojunction, Ag deposition-induced SPR effect, enhanced visible light absorption, and more surface oxygen vacancies.

Summary: The development of photocatalytic techniques for environmental remediation heavily relies on efficient charge migration and broad-spectrum optical absorption in promising photocatalysts. Ternary ZnO/ZnSe/MoSe2 heterojunctions show superior utilization efficiency of visible light and higher separation efficiency of photoinduced electron-hole pairs compared to binary counterparts. The mechanism of photocatalysis involving ZnO/ZnSe/MoSe2 is thoroughly explored, revealing enhanced degradation efficiency of pollutants and microbial sterilization.

Summary: FeWO4 was synthesized and its band structure was investigated. FeWO4 showed low photocatalytic activity for the degradation of doxycycline hydrochloride under visible light, but its activation of peroxymonosulfate greatly enhanced the degradation efficiency. The mechanism of FeWO4 activating peroxymonosulfate was proposed and confirmed through various experiments and analyses.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
