Recent trends in metal-doped carbon nitride-catalyzed heterogeneous light-driven organic transformations

Abstract

Doping carbon nitride with metal nanoparticles and metal single atoms is an efficient way to enhance the photocatalytic activity of the material for light-driven synthetic transformations. The metal-doped carbon nitride composites have also been recently demonstrated as one of the most powerful and sustainable metallaphotocatalysts in organic synthesis. A series of metals such as Pd, Ni, Cu, Fe, Co, and others have been incorporated into carbon nitride and used in photocatalytic reactions, such as cross-couplings, reductions, oxygenations, etc. These newly developed heterogeneous photocatalytic systems exhibit inherent advantages of easy separation and remarkable recyclability. In this review, we summarize the emergence, recent development, as well as unexplored aspects of the metal-doped carbon nitride in the heterogeneous photocatalytic organic transformations.
