Claim:
1. A method of preparing a metal-carbon composite supported catalyst for hydrogen production, comprising: (S1) coating a surface of an oxide-based support with carbon to form a carbon layer, and then positioning the support in a reactor; (S2) providing a metal precursor for forming a metal core and an organic precursor for forming a carbon shell to respective vaporizers, in order to be supplied to the reactor in a vaporized state wherein the metal precursor comprises one or more selected from the group consisting of a platinum precursor, a palladium precursor, a ruthenium precursor, a nickel precursor, a cobalt precursor, a molybdenum precursor and a gold precursor; (S3) feeding the metal precursor and the organic precursor, which are vaporized, into the reactor containing the oxide-based support having a carbon layer by means of a carrier gas while preventing the precursors from coming into contact with each other prior to introducing each of the vaporized precursors to the reactor; and (S4) heating the reactor and then maintaining a temperature of the reactor at a predetermined level, thus synthesizing a metal-carbon composite having the core-shell structure including the metal core and the carbon shell, the core-shell structure being supported on the oxide-based support having a carbon layer.
