Summary: The coupling of AgBr with SnO2 significantly enhances the photocatalytic activity under both UV and visible illumination, showing conversion rates superior to pure AgBr and SnO2. This improvement is attributed to increased adsorption viability and efficient separation of photoinduced carriers due to the formation of a heterojunction.

Summary: The combination of SnS2 coupling was used to modify SnO2 nanoparticles, constructing a SnS2/SnO2 heterostructure. The composites exhibited enhanced photocatalytic activity and an extended light absorption range to the visible region, leading to efficient removal of environmental pollutants. Superior photocatalytic performance was attributed to the effective separation of photoinduced carriers and enhanced light absorption.

Summary: This study demonstrates the synthesis of morphology guided copper oxide nanostructures based on the concept of Hard Acid and Soft Base (HSAB) and investigates their influence on photocatalytic activity under visible light. Different morphologies of CuO nanomaterials were synthesized using a simple chemical bath approach with various precursors of copper. Characterization of the synthesized samples was conducted using various analytical techniques. The results showed that the morphology of CuO depends on the precursor used, and the CuO synthesized using copper nitrate as a precursor exhibited excellent dye degradation performance under visible light illumination. This study provides a new approach for the synthesis of metal oxides with distinct morphologies for potential photocatalytic applications.

Summary: In response to the global issue of excessive carbon dioxide emissions, this study synthesized TiO2-rGO composite aerogels for photoconversion of CO2 using a one-step hydrothermal and freeze-drying method. The composite aerogel demonstrated improved photocatalytic performance, efficiently converting CO2 into MeOH, CH4, and EtOH through enhanced absorption capability and fast molecular transfer. The introduction of 3D rGO promoted the light absorption efficiency of TiO2 and the specific chemical bonding between rGO and TiO2 effectively mitigated electron-hole pair recombination.
