Abstract: Cobalt and copper-doped nickel Cu/Co—Ni-ferrite nanoparticles having a general formula CuxCoxNi(1-x)Fe2O4 can be a catalyst for electrooxidation of methanol in direct methanol fuel cells (DMFC). The catalyst can be an efficient anode for DMFC in alkaline electrolytes. The Cu/Co—Ni-ferrite nanoparticles can have a sponge-like structure with irregular pores. A diameter of the Cu/Co—Ni-ferrite nanoparticles can range from about 8 nm to about 30 nm.
