A platinum/black phosphorus-carbon sphere methanol fuel cell anode catalyst and preparation method thereof including the following steps: (1) dispersing a black phosphorus solid in an organic solvent to obtain a single or a few layers of black phosphorus dispersion with set concentration; (2) mixing the dispersion with glucose and stirring until dissolved; (3) performing a hydrothermal reaction on the solution to obtain an aqueous solution of the composite material containing a carbon core black phosphorus shell structure; (4) uniformly mixing the aqueous solution with an ethylene glycol solution of sodium chloroplatinate, adjusting the pH, then reducing the platinum on the surface by using a microwave irradiation heating method; and (5) filtering, washing and drying the obtained composite material to obtain a platinum/black phosphorus-carbon sphere composite material. The composite material is applied to a direct methanol fuel cell anode catalyst, the catalytic and stability performance of which are greatly improved.
