Single-site bipyridine cobalt complexes covalently embedded into graphitic carbon nitride with excellent photocatalytic activity and selectivity towards CO2 reduction

Abstract

2, 2’-bpy-5, 5’-dialdehyde copolymerized with urea to fulfill 2, 2’-bpy imbedded into the skeleton of g-CN and then chelated with Co2+ to fabricate the single-site photocatalyst g-CN-bpy-Co with excellent catalytic performance towards CO2 reduction.
