Electroless deposition of Fe-P, Fe-P-Pt alloys

Fe-P and Fe-P-Pt alloys have been developed by electroless plating techniqu e using suitable acidic bath solution and plating conditions. The alloys ar e characterised to be used as cathode materials for hydrogen evolution reac tion in alkaline solution. The alloys exhibited an overpotential of 332 (Fe -P-Pt) and 412 mVs (Fe-P) for about 70 h of continuous electrolysis in 30% KOH at a current density of 100 mA/cm(2) and temperature 323 K. The electro catalytic activity depends on the alloying elements and the composition of the alloy. Electrokinetic parameters for hydrogen evolution reaction are ev aluated.
