　　Ru-Fe-Mo-Se nano-cluster was synthesized by decarbonylation of the transition metal carbonyl compounds in 1,6-hexanediol solvent containing dissolved selenium under refluxing conditions.The catalyst powder presented a high uniformity of agglomerated nanocrystalline particles.The electrocatalytic activity of the catalyst towards oxygen reduction reaction (ORR) was investigated by the rotating disk electrode technique.The Ru-Fe-Mo-Se catalyst showed higher catalytic activity towards ORR and electrochemical stability in 0.5 mol/L H2SO4 solution,and had the open circuit potential of 0.90 V (vs.NHE).
