Summary: This study prepared two-dimensional WO3-x nanosheets with rich oxygen vacancies using solvothermal synthesis, and found that these nanosheets exhibited excellent photocatalytic activity for nitrogen fixation under visible light irradiation. The nanosheets demonstrated a significantly higher yield rate of ammonia compared to nanoparticles with poor oxygen vacancies. The presence of oxygen vacancies induced by the nanosheet structure served as active sites for chemisorption of nitrogen and facilitated electron transfer, enhancing the overall efficiency of the photocatalytic process.

Summary: Metal-organic framework (MOF) and covalent organic framework (COF) hybrid materials, with their complementary advantages and suitable band gap, have attracted significant attention in photocatalysis research. The formation of a novel sunflower-like strong pi-pi bond stacking MOF@COF hybrid platform was achieved by introducing a preformed synthetic COF into the MOF precursor solution and modulating its morphology. The synthesized MOF on the COF hybrid platform exhibited excellent catalytic activity in the photocatalytic CO2 reduction reaction under simulated sunlight, with impressive CH4 yieldrate, apparent quantum yield, and methane selectivity.
