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.
