Ni-Co/La2O3 and Ni-Cu/La2O3 bimetallic alloy catalysts were prepared by using LaNi0.9Co0.1O3 and LaNi0.9Cu0.1O3 perovskite-type oxides precursors. The results demonstrate that the components are diluted with each other in the bimetallic alloy catalyst and exhibit strong anti-sintering ability. The carbon deposited on the catalyst surface mainly depends on the adsorption state of CO; the modulated adsorption state and adsorption strength of CO contribute to the strong anti-carbon deposition ability of the Ni-Co bimetallic catalysts. The Ni-Co bimetallic alloy catalysts show remarkable activity; selectivity; and stability in the CO methanation reaction. © 2020; Science Press. All right reserved;
