Novel Pt–Ru–Ni/C Catalysts for Methanol Electro-oxidation in Acid Medium

Methanol electro-oxidation on novel Pt-Ru-Ni/C in an acid medium has been studied, and the results show an improved performance in terms of electrode activity and poisoning resistance. The performance of the Pt-Ru-Ni/C catalyst is higher than that of the Pt-Ru/C catalyst. The optimum composition has been determined by the combinatorial method. The performance of the Pt-Ru-Ni/C catalyst with an atomic ratio of 6:3:1 is the best. A peak current of 14.7 mA cm - 2 at a potential of 0.88 V, as shown by cyclic voltammetry curve, occurs.
