Published: June 26, 2021

Abstract Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due their unique morphology, high photocatalytic performance, good stability, easy synthesis, low cost. In this review, synthetic strategies developing MOFs‐based are first introduced. Second, recent progress in fabrication various MOFs composites summarized. Third, different applications including hydrogen evolution reaction, oxygen overall water splitting, nitrogen reduction carbon dioxide reaction as well photodegradation organic pollutants summed up. Finally, challenges some suggestions for future development MOFs‐ composites‐based also highlighted. It expected that report will help researchers systematically devise develop highly efficient based on composites.

Well-organized photosensitive units and catalytic sites in proximity are crucial for improving charge separation efficiency boosting photocatalysis. Herein, a general facile strategy the construction of high-loading (>4 wt %) single-atom catalysts (SACs) with tunable coordination microenvironment has been developed on basis metal-organic frameworks (MOFs). The neighboring -O/OHx groups from Zr6-oxo cluster MOFs provide lone-pair electrons balance to immobilize extraneous single metal atoms. well-accessible atomically dispersed possess close (i.e., linkers), which greatly accelerates transfer thereby promotes redox reaction. environment representative Ni significantly modulates electronic state proton activation barrier toward hydrogen production. As result, optimized Ni1-S/MOF unique Ni(I) presents excellent photocatalytic H2 production activity, up 270 fold pristine MOF far surpassing other Ni1-X/MOF counterparts. This work unambiguously demonstrates great advantage fabrication high-content SACs variable microenvironments that linkers, facilitating electron promoting
