Synergetic catalysis of a cobalt-based coordination polymer for selective visible-light driven CO2-to-CO conversion.

Abstract

Herein, based on the strategy of synergetic catalysis, we report a cobalt-based coordination polymer PEI6-Co. As a heterogeneous catalyst, PEI6-Co shows a selectivity of 95% and a yield of 1170 mmol g−1 for visible-light-driven CO2-to-CO conversion in a water containing system, which is almost 2.8 times that of the mononuclear cobalt catalyst CoL1 and is comparable to that of the dinuclear cobalt catalyst Co2L.
