NOVELTY - A core-shell type catalyst carrier comprises metal and/or metal oxide core and doped graphene, where the doped graphene has shell structure. USE - Core-shell type catalyst carrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a core-shell type catalyst carrier, which involves mixing cobalt nitrate, iron nitrate, nickel nitrate, tin chloride, zirconium nitrate, cerium nitrate, cerium chloride, cerium chloride, molybdenum chloride, aluminum nitrate, zinc chloride, gallium chloride, cerium chloride, vanadium chloride, tetraethyl orthosilicate, tetrabutyl titanate oxide precursor and polyol, and adding alkaline solution continuously stirring, where the molar ratio of precursor to polyol is 0.01-0.3:1, or stirring cobalt nitrate, iron nitrate, nickel nitrate, tin chloride, copper sulfate, barium chloride, chloroplatinic acid, chloroauric acid, palladium chloride, barium chloride, silver nitrate, barium chloride, manganese sulfate, molybdenum chloride, ruthenium chloride and chromium nitrate metal precursors and dispersing in the polyol, adding sodium hydroxide, potassium hydroxide and ammonia aqueous alkaline solution, adjusting the pH of 10-12 and centrifuging to obtain solid product, and mixing ethanol and deionized water into solid product, vacuum drying to obtain metal oxide or metal particles, heating the metal oxide or metal particles, continuously introducing an organic compound gas to carry out chemical vapor deposition to obtain the finished product.
