Bimetallic Ni@Ru nanoparticles with Ni core and Ru shell supported on SiO2 were prepared by impregnation method using a perovskite-type oxide of LaRuxNi1−xO3 as the precursor and used as catalysts for CO methanation. The catalysts were characterized by using BET, XRD, H2-TPR, HRTEM + EDX, ICP, H2 chemisorption, XPS and TGA techniques. By reducing the catalysts with hydrogen, bimetallic nanoparticles...
The critical problem for CO methanation catalysts to produce synthetic natural gas is deactivation due to carbon deposition and/or sintering of the active components. It was reported that Ni/La2O3 has better resistance to sintering and can eliminate the carbon deposited via lanthanum containing compound. However, the lanthanum oxide has low surface area, mechanical strength and stability. To overcome...
