The invention discloses a platinum and carbon sphere@zinc-iron layered double hydroxide composite material applied to direct methanol fuel cell anode catalyst. A preparation method particularly comprises the steps that a zinc-iron layered double hydroxide with a cage-shaped core-shell structure is constructed, a carbon sphere@zinc-iron layered double hydroxide serves as a carrier, platinum nanoparticles are loaded to the carrier through a sodium borohydride reduction method, and platinum and carbon sphere@zinc-iron layered double hydroxide with a novel structure is obtained. The zinc-iron layered double hydroxide has a huge specific surface area and excellent nanoparticle dispersity; according to the Pt catalyst prepared by taking the zinc-iron layered double hydroxide as the carrier, the Pt nanoparticles are uniform in dispersion and small in particle size, therefore, the electrochemical activity surface area of the catalyst is increased, and adsorption and oxidation of methanol are promoted. The zinc-iron layered double hydroxide has a rich multidimensional pore passage structure and can effectively expose the active site of the catalyst, significantly promote electron transfer in the methanol oxidation process and improve the working efficiency of a direct methanol fuel cell.
