The invention discloses a dendritic nanowire catalyst carrier with metal oxide/carbon core-sheath structure and a preparation method of a supported catalyst. The catalyst carrier is dendritic nanowires with the core-sheath structure; according to the core-sheath structure, the metal oxide is adopted as an inner core; and carbon is adopted as an outer sheath. The preparation method comprises the following steps: (1), preparing a uniform and transparent reactant solution; (2), carrying out solvothermal reaction; (3), centrifugally washing and drying the obtained product; and (4), coating the obtained product with a carbon sheath. The dendritic nanowire catalyst carrier with the metal oxide/carbon the core-sheath structure and the preparation method of supported metal nanoparticles disclosed by the invention are simple to operate and easy to control; a template is not needed in the preparation process; ordinary precursors such as chlorate and nitrate can be utilized; a metal organic compound required for preparation of the catalyst with a special structure is avoided; and the cost is further reduced.
