Photochemical CO₂ reduction in water using a co-immobilised nickel catalyst and a visible light sensitiser

Abstract

A dye-sensitised CO₂ reduction photocatalyst that operates in water is reported. Transient spectroscopy demonstrates that the facile co-immobilisation of a Ru dye and a Ni CO₂ reduction electrocatalyst enables efficient on-particle electron transfer leading to photocatalytic activity that greatly exceeds the equivalent solution based system.
