Abstract:
Herein, neutral mononuclear indium(III) complexes (In-1-In-3) containing 2,6-di(1H-pyrrol-2-yl)pyridine and substituted dipyridylpyrrole pincer ligand were employed as photosensitizers (PS) in photocatalytic CO2 reduction. In-2 exhibits good photo-activity and selectivity, which is superior to the classic PS Ru(bpy)32+. The amount of CO generation is 28.4 μmol with a CO selectivity of 93% when using In-2 as a PS and CoPc as a catalyst in CH3CN media.
