(57) [Summary] [Objective] To produce a supported catalyst containing palladium, platinum, nickel, cobalt or copper on an airgel as a support. A mixture of an aerogel alkoxide precursor and a chelating agent having a Si (OR 1 ) 3 anchor group and a soluble chelate complex of, for example, palladium, The precursor is hydrolyzed and the resulting gel is transferred to a transition metal-aerogel supported catalyst under supercritical conditions. [Effect] This catalyst has a particularly homogeneous distribution of metal components and is suitable for use as a hydrogenation catalyst. |
