Summary: The combination of photocatalysis-driven H2O splitting and thermal catalysis-supported CO2 reduction with photothermal CO2 reduction using H2O has attracted interest in artificial synthesis of solar fuel. In order to improve the redox capacity, hollow boxwood ball-like WO3/WS2 Z-scheme heterojunctions were prepared for photothermal catalytic CO2 reduction. The formation of the Z-scheme heterojunction promotes rapid carrier transfer and improves light utilization, while the WO3/WS2 heterostructure utilizes its unique LSPR effect to generate heat and promote molecular activation. This work demonstrates a promising approach for designing photothermal catalytic CO2 reduction using TMDCs-based catalysts.

Summary: The Z-scheme ZnO/Au/g-C3N4 micro-needle film enhanced by the Local Surface Plasma Resonance (LSPR) effect demonstrated excellent photocatalytic performance and reusability in the photoreduction of CO2 into CO under UV-vis light irradiation. The material achieved a high CO production rate after 8 hours of reaction time, which was significantly higher than that of the pure ZnO film. The combination of factors such as the electric field at the g-C3N4/ZnO interface, the role of Au NPs as electron-transfer bridges and LSPR excited sources, and in-situ FTIR technique investigation contribute to the enhanced electron transfer efficiency and overall photocatalytic performance.

Summary: A novel In2O3/AgI heterojunction with a hollow tubular structure and evenly distributed AgI particles on In2O3 microtubes was fabricated and showed much higher photocatalytic activity towards tetracycline degradation than In2O3 and AgI. The presence of InAg-1 achieved 98.4% removal of tetracycline in 10 minutes under visible light illumination and demonstrated excellent reusability and stability. The heterojunction also exhibited excellent performance in different water matrices and under natural sunlight, indicating its potential in practical applications. The superior photocatalytic activity is attributed to the heterojunction formation, oxygen vacancies, and the formation of a Z-scheme heterojunction between In2O3 and AgI.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
