Abstract
Provided are a noble metal-transition metal complex catalyst supported on a carbon-coated silica-alumina support and a preparation method therefor, the catalyst being capable of obtaining a fast reaction rate and catalyst stability, as compared to a conventional catalyst, when cyclohexane dimethanol (CHDM) production is carried out by a cyclohexane dicarboxylic acid (CHDA) hydrogenation reaction in an aqueous solution by using a carbon-coated supported catalyst.
