Resumen
Oxygen reduction nanometric trimetallic RuXMo (X=Se, Sn) electrocatalysts have been prepared by mechanical alloying. The nanostructured catalysts were characterized by X-ray diffraction and Scanning electron microscopy. Homogeneous catalysts particles supported on Vulcan carbon were investigated by rotating disk electrode for the oxygen reduction reaction (ORR) in 0.5 M H2SO4. Results reveal improved specific activities toward the ORR with multielectron transfer process (n=4e-) to water formation. The RuSnMo presented a slightly higher electrocatalytic activity than RuSeMo due to its structural characteristics
