Photocatalytic activity of carbon nitride modified with a ruthenium(II) complex having carboxylic- or phosphonic acid anchoring groups for visible-light CO2 reduction

Abstract

Semiconducting C3N4 powder modified with a catalytic Ru(II) complex having carboxylic acid groups as anchors showed higher activity for CO2 reduction into HCOOH under visible light (λ > 400 nm) at the initial stage of the reaction, whereas an analogue anchored with phosphonic acid groups exhibited higher stability.
