报告简介:CO2 hydrogenation to C1 chemicals has attracted significant interest due to the increasing demand of energy and global warming. Continuous efforts in the field of heterogeneous catalysis have revealed that the CO2 hydrogenation is structure sensitive in monometallic catalysts. However, the structure-performance relationship fundamental research in bimetallic catalysts is a big challenge because the well-defined bimetallic structures and the corresponding mechanism are more complex than monometallic ones. Here, with the construction of TiO2 supported Ni-Ru bimetallic catalysts, evidenced by advanced microscopy characterizations, the alloyed and nonalloyed structures have been synthesised for the hydrogenation. The in-situ experiments show that the Ni-Ru bimetallic structures act like an‘H atom-valve’ via controlling the H2 spillover which can completely switch the CO2 hydrogenation selectivity during the reaction. These findings bring a fundamentally new understanding of the selective hydrogenation on bimetallic nano-catalysis and the structure-performance relationship in controlling the ‘H atom-valve’ for many important chemical processes.
