A novel sol-gel process of preparation of oxide electrocatalysts is in
vestigated to prepare Ni-containing mixed oxides LaNiO3 and NiCo2O4 at
moderate temperatures. High surface area (20-55 m(2) g(-1)) powders a
nd high roughness electrodes (30-1500) were obtained. Apparent and rea
l electrocatalytical activity are compared and discussed. (C) 1995 Aca
