Synergistic Bifunctional Covalent Organic Framework for Efficient Photocatalytic CO 2 Reduction and Water Oxidation

The scientific community has been actively researching artificial photosynthesis to promote ecologically sustainable living and address environmental issues. However, designing photocatalysts with active sites that are effective for both CO2 reduction and water oxidation remains a significant challenge. Thus, we present the development of a donor–acceptor covalent organic framework (D–A COF), that integrates two distinct metal coordination environments through structure–activity relationships. Either cobalt or nickel ion is anchored on the D–A COF backbone to create N-metal–nitrogen and N-metal–sulfur coordination configurations, serving as bifunctional reduction and oxidation active sites, respectively.…
