Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(23)

Published: April 23, 2023

Abstract Benefitting from ultra‐high porosity, large specific surface area (SSA), and rich active sites, metal–organic frameworks (MOFs) have emerged as a star material in energy environment related applications, especially photocatalysis. In comparison with conventional photocatalysts, MOFs can be customized terms of electronic structure, photo‐responsiveness, morphological dimensions by rational design, which means that eliminate the need for other species to achieve enhanced photocatalytic performance, such metals, compounds, polymers, may introduce extra costs, time‐consuming, multi‐phase, or an unclear mechanism. Most previous review works MOF photocatalysis mixed self‐tuning assisted‐tuning, often gives incomplete understanding. this work, self‐tunning analyzing component (as clusters, ligands, inclusions), defect (defect engineering, linkers, oxygen vacancies (OVs), crystal facets, dimensions, amorphization) is summarized. Then, outstanding examples these strategies applied water redox, CO 2 /N reduction, organic conversion, environmental treatment are discussed. Finally, opportunities challenges faced analyzed different perspectives. This paper comprehensive systematic on enhance activity.

Integrating electron donor and acceptor chromophores as ligands within one MOF for light harvesting photocatalysis appears to be a major synthesis challenge. Meanwhile, high-efficiency selective aerobic oxidative coupling of amines imines under mild conditions is highly desirable scientific industrial fields. Herein, via facile one-pot synthetic strategy, an porphyrin ligand 5,15-di(p-benzoato)porphyrin (H2DPBP) was successfully integrated into naphthalene diimide (electron acceptor)-based Zr-MOF (Zr-NDI) construct mixed-ligand (Zr-NDI-H2DPBP) benefiting from the two with similar geometry connectivity. When utilized heterogeneous photocatalyst benzylamine at room temperature, prepared Zr-NDI-H2DPBP exhibited boosted imine generation rate (136 mmol g–1 h–1) far exceeding those other noble-metal-free photocatalysts can applied various derivatives. Furthermore, results experiments density functional theory calculations, photocatalytic performance attributed photoinduced transfer H2DPBP NDI energy facilitated by photosensitized irradiation, which effectively improve electron–hole separation efficiency generate abundant reactive active species superoxide radical (O2•–) singlet oxygen (1O2), respectively. This work provides avenue chromophore-based light-harvesting systems utilizing MOFs platforms boost solar-energy conversion.
