Summary: In this study, CdS quantum dots and Ni2+ were incorporated into layered calcium niobate perovskite KCa2Nb3O10 to achieve efficient visible-light photocatalytic hydrogen production. The photocatalytic activity was significantly enhanced with the increase of the interlayered Ni content. The highly efficient activity can be attributed to the heterojunction structure, which effectively inhibits the recombination of photo-generated electron-hole pairs.

Summary: Rationally designing heterojunction photocatalysts with well-defined nanostructures and intimate interfacial contact significantly improves the photocatalytic hydrogen evolution reaction (HER) activity. The 1D CdS/2D MoSe2 heterostructure exhibited an enhanced hydrogen-evolving rate of 25.8 mmol g(-1) h(-1) with an apparent quantum efficiency of 30% at 420 nm, attributed to the synergistic effect between the CdS nanorods and MoSe2 nanosheets in accelerating electron-hole separation and interfacial charge transport. This study suggests that morphology control and interfacial engineering can effectively tune the efficiency and long-term stability of heterojunction photocatalysts for hydrogen production, providing insights for robust high-performance visible light photocatalysts.

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.
