The invention discloses a platinum-carbon composite nano-catalyst as well as a preparation method and an application of the platinum-carbon composite nano-catalyst. The preparation method of the catalyst comprises a step of loading platinum on a surface-modified carbon material to obtain a platinum-carbon composite nano-catalyst, wherein the surface-modified carbon material is rich in electron-deficient surface defects and electron-deficient surface oxygen-containing functional groups.
