The effect of enantioselective chiral covalent organic frameworks and cysteine sacrificial donors on photocatalytic hydrogen evolution

Weijun Weng et al.

Summary: Covalent organic frameworks (COFs) have shown great potential as organic photocatalysts for hydrogen evolution from water under visible light. However, their reaction kinetics are slow and often require precious metal co-catalysts. In this study, a chiral COF coordinated with atomically dispersed Cu(II) was synthesized, and the combination of the chiral COF-Cu(II) skeleton with sacrificial donors remarkably improved the hole extraction kinetics and facilitated the transfer of photoinduced electrons. The parallel stacking sequence of chiral COFs also provided a favorable arrangement for hydrogen adsorption. As a result, the visible photocatalytic hydrogen evolution rate reached a high value of 14.72 mmol h(-1) g(-1) without precious metal co-catalysts. This study presents a strategy for optimizing reaction kinetics and demonstrates the promising potential of chiral COFs for photocatalysis.
