Facile electron delivery from graphene template to ultrathin metal-organic layers for boosting CO2 photoreduction

Abstract Metal-organic layers with ordered structure and molecular tunability are of great potential as heterogeneous catalysts due to their readily accessible active sites. Herein, we demonstrate a facile template strategy prepare metal-organic uniform thickness three metal coordination (ca. 1.5 nm) graphene oxide both electron mediator. The resulting hybrid catalyst exhibits an excellent performance for CO 2 photoreduction total yield 3133 mmol g –1 MOL (CO selectivity 95%), ca. 34 times higher than that bulky Co-based framework. Systematic studies reveal well-exposed sites in layers, transfer between homogeneous components mediated by oxide, greatly contribute its high activity. This work highlights way constructing ultrathin demonstrates charge pathway conductive boosting photocatalysis.
