英文摘要：The vacancies of semiconductor have been proven to be effective active sites for photocatalytic nitrogen fixation, but what about the role of defects in MOF materials? Here we report the first UiO-66 with photo-excited cluster defects and linker defects for photocatalytic nitrogen fixation. It''s determined through the post-synthetic ligand exchange (PSE) process that the linker defects rather than cluster defects can greatly improve the performance, which due to the linker defects formed unsaturated metal nodes like the vacancy in semiconductor. Specifically, for photo-activated UiO-66, the NH4+ production rate was 196 and 68 μmol g-1 h-1 in air atmosphere under Ultraviolet-Visible (UV-vis) and visible light, respectively. This report provides a new effective strategy to design efficient nitrogen fixation photocatalysts.
