Photochemical reduction of CO₂ is very meaningful to relieve the energy crisis and environmental deterioration. A Cu^II complex shows high catalytic activity for the reduction reaction of CO₂ to CO driven by visible light in 4:1 acetonitrile/water (v:v) using [Ru(phen)₃](PF₆)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.

光化学还原CO ₂对于缓解能源危机和环境恶化非常有意义。Cu ^II络合物在使用[Ru（phen）₃ ]（PF ₆）₂作为光敏剂并在4：1乙腈/水（v：v）中，对可见光驱动的CO ₂还原为CO的反应具有高催化活性。三乙醇胺作为牺牲性还原剂，具有9900的高TON和98％的高选择性。同位素标记实验，耐久测试和能量色散光谱分析的结果表明，这种铜^II络合物在光催化过程中很坚固。有关更多信息，请参见《直流电通讯》。钟伯T 卢，等。在第4503页。
