This report includes the preparation of a new set of well-defined Cu(I) catalytic precursors of the type [Cu(diphosphine)(PPh₃)NO₃] and [Cu(diphosphine)NO₃], fully characterized by regular analytical methods, including single-crystal XRD (X-ray diffraction). The new compounds were assessed to activate CO₂ in an electrocatalytic process to yield oxalate selectively and with a relatively low overpotential. Some mechanistic insights into this process are also provided; oxalate is a valuable product for further chemical applications.

新型单核 Cu(I) 化合物：合成、表征及其在 CO2 电还原中的应用


本报告包括制备一组新的明确定义的 Cu( I ) 催化前体，其类型为 [Cu(二膦)(PPh ₃ )NO ₃ ] 和 [Cu(二膦)NO ₃ ]，并通过常规分析方法进行了充分表征，包括单晶 XRD（X 射线衍射）。评估新化合物在电催化过程中活化CO ₂以选择性地产生草酸盐并具有相对较低的过电势。还提供了对该过程的一些机械见解；草酸盐是一种有价值的产品，可用于进一步的化学应用。
