dc.description.abstract | Ruthenium catalysts modified by selenium have been introduced as alternative materials to Pt in Direct methanol fuel cells (DMFCs) RuSe nano-particles were synthesized on the Vulcan XC72R carbon supports via polyol method The prepared catalysts were electrochemically and physically characterized by cyclic voltammetry (CV,) linear sweep voltammetry, methanol tolerance test, X-ray diffraction (XRD), Transmission electron microscopy (TEM), Energy-dispersive Spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS) Increasing the Se concentration up to 20 at % increased the electro-catalytic activity for the oxygen reduction By increasing Se amount, Ru metallic form on the surface was increased The Ru80Se20/C catalysts showed the highest oxygen reduction reaction (ORR) activity and outstanding methanol tolerant property in half cell tests as well as single cell test | - |
