新型催化剂将二氧化碳高效转化为丙烷

Core Insights - The research team at Anhui Normal University has made significant progress in the field of photocatalytic carbon dioxide reduction, successfully converting CO2 into high-value propane through the design of multi-site cooperative catalysts [1][2] Group 1: Research and Development - The team developed an atomic-level catalyst based on metal-organic framework materials, utilizing NH2-MIL-125 (Ti) nanosheets as a carrier, which features a cooperative active center composed of nickel single atoms and adjacent manganese double atoms [1] - The study reveals that the high selectivity for propane generation is due to the synergistic mechanism between nickel and manganese active sites, where nickel activates CO2 and converts it into carbon monoxide intermediates, while manganese promotes carbon-carbon bond formation [2] Group 2: Implications and Applications - This research provides a new strategy for designing efficient and selective CO2 reduction catalysts, advancing the fundamental research in photocatalytic carbon conversion and opening new pathways for the resource utilization of greenhouse gases and the synthesis of green chemical raw materials [2]
