摘要：

Cathode materials with high catalytic activity for the hydrogen evolution reaction were developed by using metal ultra-fine particles (UFPs) of Ni and Mo. Ni UFPs sintered at about 573 K were extremely porous and had an enormously large surface area. The measured hydrogen overpotential of the Ni UFPs in sulfuric acid solution was shown to be as low as that of Pt. Further decrease in hydrogen overpotential was observed when Mo UFPs were mixed with the Ni UFPs. Copyright (C) 1996 International Association for Hydrogen Energy
