摘要：
The hydrogen evolution reaction was studied on vacuum plasma sprayed Ni-Al and Ni-Al-Mo electrodes in 1 M NaOH and 25% KOH at 70 degrees C. It was found that Ni-Al-Mo electrode is more active in 25% KOH whereas Ni-Al electrode was more active in 1 M NaOH solutions. A.c. impedance measurements showed two semicircles on the complex plane plots. Two different equivalent models were used to explain this behaviour. The results indicate that the formation of the second semicircle is connected with the hydrogen evolution reaction.
