中国科学院大连化学物理研究所基于“纳米限域催化”概念,创造性地构建了硅化物晶格限域的单中心铁催化剂,实现了甲烷在无氧条件下的选择活化,可一步高效生产乙烯、芳烃等高值化学品。大连化物所的研究人员将具有高催化活性的单中心低价铁原子通过2个碳原子和1个硅原子镶嵌在氧化硅或碳化硅晶格中,形成高温稳定的催化活性中心;甲烷分子在配位不饱和的单铁中心上催化活化脱
Dalian Institute of Chemical Physics, Chinese Academy of Sciences Based on the concept of “nano-confinement catalyst ”, a single-site iron catalyst with silicide lattice confinement was creatively constructed to realize the selective activation of methane under anaerobic conditions and can be efficiently produced in one step Ethylene, aromatic and other high-value chemicals. Researchers in Dalian Institute of Chemical Technology will be highly catalytically active single-center low-cost iron atoms through 2 carbon atoms and a silicon atom embedded in the silicon oxide or silicon carbide lattice, the formation of high temperature stable catalytic activity center; methane molecules in Coordination of unsaturated iron center catalytic activation off
