Various Ru/TiO2 catalysts in powder form were prepared by a dry processing named “barrel-sputtering”. Hydrogenation of CO2 to methane successfully proceeded on the catalysts at temperatures below 300 C without the formation of carbon monoxide (CO) even if pretreatment of the catalysts was carried out. It is noteworthy that catalytic activity of Ru/TiO2 catalyst was enhanced when the catalyst was immobilized in a three-dimensional structure. In addition, use of the immobilized catalysts resulted in significant alleviation of not only catalyst weight but also temperature differences in the reactor., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: DS1440077000}, pages = {86--93}, title = {宇宙実用化を目指したサバチエ反応触媒の開発}, volume = {30}, year = {2013} }
