In the photocatalytic conversion of CO2 to valuable chemicals under aqueous conditions, the selectivity and the product yield still present the most challenging issues. Against this backdrop, negatively charged water-soluble CdS nanocrystals were used to assemble with a positively charged dinuclear cobalt complex through electrostatic interactions. This assembly efficiently catalyzes the CO2-to-CO conversion under visible light, with a high selectivity of 95%, a high yield of 34.51 μmol of CO, and a large turnover number (TON) of 1380 based on the cobalt catalyst, all of which are record high values for a noble-metal-free visible-light-driven CO2 reduction system with a molecular catalyst in a fully aqueous medium.

CdS纳米晶体与双核钴催化剂的静电组装在水中选择性光催化还原CO 2
在水性条件下将CO 2光催化转化为有价值的化学物质时，选择性和产物收率仍然是最具挑战性的问题。在这种背景下，带负电的水溶性CdS纳米晶体用于通过静电相互作用与带正电的双核钴配合物组装。基于该钴催化剂，该组件可有效催化可见光下的CO 2转化为CO，转化率高达95％，CO收率高达34.51μmol，并且营业额（TON）高达1380。其中，在完全水性介质中使用分子催化剂的无贵金属无可见光驱动的CO 2还原系统的记录值很高。
