摘要：
A porous carrier for a catalyst comprising metal coated with metal oxide grains having a mean grain size of 150 nm or less and a mean pore diameter of 5.5 nm or less, is obtained by subjecting:(a) stainless steel;(b) (i) a metal alkoxide or (ii) a metal alkoxide and a metal acetate salt, both being soluble in alcohols;(c) a diol, cellosolve, or polyether which has coordinating capacity with the (i) metal alkoxide or (ii) metal alkoxide and metal acetate salt and which is soluble in alcohols; and(d) an alcohol solvent to hydrolysis and polycondensation, whereby the stainless steel is coated with an oxygen-containing organic metal compound and, subsequently, heat-treated to form a metal oxide. A method of preparing the catalyst is also provided.
