A non-noble metal oxygen reduction reaction （ORR） catalyst labeled as Co-C-N（800） was synthesized by heat-treating a mixture of urea, cobalt chloride and acetylene black for 2 h at 800 ℃ in an inert nitrogen atmosphere. X-ray diffraction pattern indicates that a metallic β-Co is generated after the heat-treating process. The results from cyclic voltammograms show that the obtained Co-C-N（800） catalyst has good ORR catalytic activity in 0.5 mol/L H2SO4 solution. The catalyst is also good at methanol tolerance and stability in the acidic solution.
