摘要
PROBLEM TO BE SOLVED: To obtain a new catalyst capable of efficiently modifying carbon dioxide by supporting rhodium on one or more kind of a carrier selected from among oxide of group II, III, IV metal and a lanthanide metal oxide compd. or a composite carrier of alumina containing those metal oxides. SOLUTION: One or more kind of a carrier selected from among oxide of group II, III, IV metal and a lanthanide metal oxide or a composite carrier of those oxides and alumina is used and rhodium is supported on this carrier. As a rhodium supporting method, a known method such as an impregnation method or the like can be used. The supporting amt. of rhodium is set to 0.5-5wt.%, especially pref. 0.5-3wt.%. The carrier on which rhodium is immobilized is dried pref. at below 200 deg.C, more pref. at 150 deg.C or lower, especially pref. at 100 deg.C or less. It is necessary to reduce the supported rhodium catalyst before modifying reaction. As a reducing gas, it is pref. to use hydrogen gas.
