New non-platinum Ir–V–Mo electro-catalyst, catalytic activity and CO tolerance in hydrogen oxidation reaction

Very active 40%Ir–10%V–3%Mo/C and 40%Ir–10%V–10%Mo/C (in weight) catalysts, as novel, suitable anode electrode materials in polymer electrolyte membrane fuel cells (PEMFCs), have been synthesized by an ethylene glycol (EG) reduction method. The nanostructured catalysts have been characterized by X-ray diffraction (XRD) and high-resolution transmission electron microscopy (TEM). Ir nanoparticles, after modification with V and further with Mo, …
