Controlling the Reconstruction of Ni/CeO2sub> Catalyst during Reduction for Enhanced CO Methanation Article

Xinyu Cao,Tiancheng Pu,Bar Mosevitzky Lis,Israel E. Wachs,Chong Peng,Minghui Zhu,Yongkang Hu,

Engineering 2022, Volume 14, Issue 7, Pages 94-99 doi: 10.1016/j.eng.2021.08.023

Abstract:

Reductive pretreatment is an important step for activating supported metal catalysts but has received little attention. In this study, reconstruction of the supported nickel catalyst was found to be sensitive to pretreatment conditions. In contrast to the traditional activation procedure in hydrogen, activating the catalyst in syngas created supported Ni nanoparticles with a polycrystalline structure containing an abundance of grain boundaries. The unique post-activation catalyst structure offered enhanced CO adsorption and an improved CO methanation rate. The current strategy to tune the catalyst structure via manipulating the activation conditions can potentially guide the rational design of other supported metal catalysts.
