Carbon Dioxide Electroreduction: Efficient Electron Transfer from Electron‐Sponge Polyoxometalate to Single‐Metal Site Metal–Organic Frameworks for Highly Selective Electroreduction of Carbon Dioxide (Small 20/2021)

By combining the superiority of polyoxometalate (POM) and single-metal site Co in porphyrin, a POM-based metal–organic framework composite has been constructed by Wen-Wen He, Ya-Qian Lan, Shengqian Ma, and co-workers (article number 2100762). Directional electron transfer from POM to the single-metal site Co in PCN-222(Co) accelerates electron-transfer efficiency thereby affording high electrocatalytic CO2 reduction reaction activity.
