摘要：
Platinum-sulphide electrocatalyst, in the nano-scale length, supported on carbon (PtxSy/C) was obtained by thermal treatment (350 degrees C) of the chemical precursor which was generated by reacting sulphur and salts of platinum at room temperature. Cyclic voltammetry, and rotating disk electrode electrochemical measurements in methanol containing acid electrolyte revealed that the chalcogenicle material is 95% selective, as compared to commercial Pt/C, in methanol for the oxygen reduction reaction.
