| Abstract | Introduction To reduce the total manufacturing cost of residential fuel cell systems, development of a simplified fuel processor is a major obstacle. For this reason, replacement of the conventional CO removal process (preferential CO oxidation, PROX) with a new CO removal process, i.e., “selective CO methanation reaction” should be a promising approach. We have reported excellent catalytic performance for the reaction of novel Ni-based catalysts prepared by the solution-spray plasma technique [1] and solution vaporization-induced technique [2]. Through those techniques, Ni/alumina catalysts with high Ni dispersion were facilely synthesized. In this study, for the further improvement of catalyst durability, we developed a mesoporous silica-covered Ni-based catalyst. 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 in detail. |
