摘要：
A novel sol-gel process of preparation of oxide electrocatalysts is investigated to prepare Ni-containing mixed oxides LaNiO3 and NiCo2O4 at moderate temperatures. High surface area (20-55 m(2) g(-1)) powders and high roughness electrodes (30-1500) were obtained. Apparent and real electrocatalytical activity are compared and discussed.
