<p>Provided are a precious metal-supported catalyst comprising: 100 parts by weight of carbon carrier which has uniform pore structure; 1-20 parts by weight of transition metal supported on the carbon carrier; and 1-10 parts by weight of precious metal supported on the carbon carrier, having a specific surface area of greater than or equal to 450 m^2/g, and preparing a mixture of 1,4-butanediol and dimethylsuccinate from a solution including succinic acid, and a method for preparing the precious metal-supported catalyst. Also, provided is a novel catalyst reaction process which can effectively prepare 1,4-butandiol from succinic acid using the precious metal-supported catalyst.</p> |
