Published: Jan. 1, 2023

Photocatalytic organic reactions, harvesting solar energy to produce high value-added chemicals, have attracted increasing attention as a sustainable approach address the global crisis and environmental issues. Reticular framework materials, including metal-organic frameworks (MOFs) covalent (COFs), are widely considered promising candidates for photocatalysis owing their crystallinity, tailorable pore environment extensive structural diversity. Although design synthesis of MOFs COFs been intensively developed in last 20 years, applications photocatalytic transformations still preliminary stage, making systematic summary necessary. Thus, this review aims provide comprehensive understanding useful guidelines exploration suitable MOF COF photocatalysts towards appropriate reactions. The commonly used reactions categorized facilitate identification reaction types. From practical viewpoint, fundamentals experimental design, active species, performance evaluation external conditions, discussed detail easy experimentation. Furthermore, latest advances COFs, composites, comprehensively summarized according actual sites, together with discussion structure-property relationship. We believe that study will be helpful researchers novel reticular various synthetic applications.

Ligand Modification of Au₂₅ Nanoclusters for Near-Infrared Photocatalytic Oxidative Functionalization

Journal of the American Chemical Society, Journal Year: 2022, Volume and Issue: 144(9), P. 3787 - 3792

Published: Feb. 28, 2022

The inorganic-organic interface between metal catalysts and their substrates greatly influences reaction processes, but few studies of this have been conducted for a detailed understanding its structure. Herein, we describe the synthesis structural determination an arylthiolated Au25(F-Ph)18- nanocluster characterize in detail key roles ligands photocatalyzed oxidative functionalization reactions. most significant findings are that (i) interactions established to avoid distortion geometric structure, limit Jahn-Teller effect, protect from oxidization (ii) low energy gap (HOMO-LUMO) synthetic clusters enables three types photocatalytic reactions by near-infrared light (850 nm).
