Photochemical reduction of CO 2 is very meaningful to relieve the energy crisis and environmental deterioration. A Cu II complex shows high catalytic activity for the reduction reaction of CO 2 to CO driven by visible light in 4:1 acetonitrile/water ( v : v ) using [Ru(phen) 3 ](PF 6 ) 2 as a photosensitizer and triethanolamine as a sacrificial reductant, with a high TON of 9900 and a high selectivity of 98%. The results of isotope labeling experiments, durable testing and energy dispersive spectroscopy reveal that this Cu II complex is robust during the photocatalytic process.
