Abstract
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.
