Recently, Huang Jiahui's team and Fu Qiang's team from Dalian Institute of Chemistry, Chinese Academy of Sciences cooperated with Si Rui, a researcher from Shanghai Institute of Physics, Chinese Academy of Sciences, to reveal the synergistic catalytic mechanism in double monatomic catalysts. Related research results are published in ACS Catalysis.

Monoatomic catalysis is one of the research hotspots in the field of heterogeneous catalysis. Double monoatomic catalysts have two sets of monoatomic structures, and the two sets of monoatomic structures can play different roles in catalytic reactions. The synergistic effect of the two can not only maximize the utilization rate of atoms, but also improve the selectivity of catalysis. Double monatomic synergistic catalysis provides a good platform for understanding bimetallic synergistic effect at atomic level.

It was found that in the selective hydrogenation of p-nitrobenzene, the selectivity of titanium dioxide supported iridium-molybdenum bimonoatom catalyst (IR1Mo1TiO _ 2) to 4- aminostyrene was more than 96%, which was much better than that of titanium dioxide supported iridium-molybdenum monomonoatom catalyst (IR1TiO _ 2) and titanium dioxide supported molybdenum monomonoatom catalyst (Mo65438).
