Summary: The cation exchange method was used to synthesize water dispersed ZnSe/Bi2Se3 core/shell quantum dots with varying Bi content, allowing for tunability in shell thickness and subsequently affecting structural and optical properties. The formation of Bi2Se3 shell was confirmed by shifting peak positions in XRD and Raman spectra, as well as shifting XPS peaks. Increasing shell thickness enhanced band edge absorption and decreased optical bandgap. Broad photoluminescence emission with multiple components was observed for all samples. The ZnSe/Bi2Se3 quantum dots showed good antibacterial activity against Staphylococcus aureus (ATCC 25,923).

Summary: Metal-halide perovskite quantum dots (QDs) have been developed as a potential photocatalyst, but their stability and charge transportation efficiency limitations hinder their applications. By decorating CsPbBr3 QDs on two-dimensional g-C3N4 (UCN) nanosheets, a composite photocatalyst with improved stability and charge transfer efficiency was successfully developed, showing superior photocatalytic performance compared to pristine CsPbBr3 QDs and UCN. This work provides an efficient strategy for designing CsPbX3-based heterostructures with high stability and photocatalytic activity.

Summary: Photocatalytic reduction of CO2 into valuable hydrocarbon fuels is a green way to solve the energy problem and achieve carbon neutrality. This study presents a lead-free halide perovskite-based 0D/2D Cs3Bi2Br9/Bi2WO6 S-scheme heterojunction with superior CO2 photoreduction activity under visible light. The improved photocatalytic performance can be attributed to the tight 0D/2D structure and S-scheme charge transfer pathway, which shortens transmission distance of photogenerated carriers and boosts efficient separation and transfer of the carriers. This work provides insights into potential lead-free perovskite-based photocatalysts for achieving carbon neutrality.

Summary: The photodegradation of ampicillin over illuminated Ag2Te/ZnTe nano-catalyst was studied in this research, and the physico-chemical attributes of the catalyst were found to significantly influence the degradation performance. By increasing the content of Ag2Te in the hybrid catalyst, the band gap of the catalyst was reduced and the photodegradation efficiency was enhanced. The optimized conditions for maximum degradation efficiency were found to be neutral pH, a nano-catalyst dose of 1.0 g/L, and an AMP concentration of 10 mg/L.

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.
