Abstract

Abstract A mesoporous silica-coated Ni/alumina-based catalyst was developed for selective CO methanation, which is a promising candidate as a new hydrogen purification process for a residential PEFC system. Over the new catalyst, CO removal activity and durability were dramatically improved. In this study, the structure of the catalyst and mechanism for the improvement of catalytic performance will be discussed.
