“…The HER at a Pd-Ni electrodeposited alloy electrode has been studied owing to its high HER activity by the combination effect [9] in expectation. Many scientists also made large efforts to search other novel materials for HER catalysis [10][11][12]. On one hand, it was reported that the noble metals are the most active materials for HER catalysis [13,14].…”

Nickel and nickel-cerium (Ni-Ce) alloys with different amounts of Ce (5 and 10 at.% Ce) have been prepared by arc melting and characterized by scanning electron microscopy and electron probe microanalysis based on energy dispersive X-ray spectroscopy, to investigate microstructure and to determine phase composition. Subsequently, Ni and Ni alloy-based electrodes were fabricated and studied for borohydride (BH4 -) oxidation in alkaline media by cyclic voltammetry and chronoamperometry in the temperature range 25 -45 ºC. Preliminary results showed comparable BH4 -oxidation peak current densities obtained at three electrodes, with Ni95Ce5 electrode giving the highest current densities. Electrochemical data are modelled to obtain relevant kinetic parameters of BH4 -oxidation at these electrodes. Effect of electrolyte temperature on the evaluated parameters has been investigated as well.

“…In general, the main operational issues of the DBPFC are the hydrolysis and thus incomplete BH 4 À anodic electrooxidation [4] and the mentioned chemical decomposition of H 2 O 2 at the cathode [5]. Therefore, the development of anode and cathode electrocatalysts having high selective catalytic activities for BH 4 À oxidation and H 2 O 2 reduction, respectively, has been a key point in DBPFC research [6][7][8][9][10][11]. Platinum-based catalysts, similarly to gold, palladium and silver, possess good catalytic activity for H 2 O 2 reduction reaction (HPRR) but have the disadvantage of high cost [9].…”
