Abstract
A method of preparing a catalyst containing at least two metals captured on a porous support, at least one of the metals being capable of forming a reducible oxide, includes the steps of providing solutions of the two metals, impregnating the support with the solution of the metal which is capable of forming a reducible oxide, exposing the impregnated support to a reducing atmosphere at a temperature exceeding 300.degree. C. and impregnating the thus treated support with the other solution.
Claims17
A method of preparing a catalyst containing at least two metals captured on a porous support, at least one of the metals being a transition metal and the other being gold, including the steps of providing solutions of the metals, impregnating the support with the solution of the transition metal, exposing the impregnated support to a reducing atmosphere at a temperature exceeding 300.degree. C., impregnating the thus treated support with the solution of gold, and exposing the support, impregnated with both of the solutions, to a temperature exceeding 300.degree. C. in an oxidizing atmosphere.
