Sumario: | [Image: see text] The conversion of carbon dioxide (CO(2)) into organic carbonates under ambient temperatures and pressures with high conversion and selectivity still faces a great challenge. The zerovalent atomic catalysts (ACs), featuring accurate structure and valence states, provide a new and accurate model system for catalysis. Herein we developed a general preadsorption-reduction strategy to synthesize zerovalent cobalt AC on graphdiyne (Co(0)/GDY). The Co(0)/GDY ACs were used for efficient and selective CO(2) fixation. We were surprised to find that Co(0)/GDY ACs reached nearly 100% conversion at 80 °C and 1 atm in CO(2) fixation and with a significantly high turnover frequency (TOF) of 3024.8 h(–1), which is almost several orders larger than that of benchmarked catalysts. Such high conversion and selectivity represent the advantages of emerging catalysts. |
