英文摘要Hydrogenation of CO2 into CH4 is an effective strategy for dealing with CO2-relevant environmental problems. Since the CO2 methanation reaction involves multiple electron transfers and various C-1 intermediates, improving the reaction rate at each step is critical to accelerating the entire reaction. Here, we report a dual-active-site tandem catalyst (Ru1Ni/CeO2) composed of Ru single atoms (Ru-1) and Ni nanoparticles, which can effectively convert CO2 to CH4, showing similar to 90% CO2 conversion and similar to 99% CH4 selectivity at 325 degrees C, much higher than those of the Ru-1/CeO2 and Ni/CeO2 catalysts. Experimental and theoretical calculation results reveal that Ru-1 is extremely active for converting CO2 to CO, while the Ni site is highly efficient for the subsequent sequential CO to CH4 reaction step. The coexistence of the Ru-1 and Ni sites significantly boosts the overall reaction. This work offers a promising strategy for the rational design of efficient multisite tandem catalysts.
