摘要
Abstract
Perovskite LaNiO3 which is used in bifunctional oxygen electrode is prepared by the sol-gel method using citric acid as complexing agent. Products are characterized using TG-DTA, XRD, SEM, et al. It showed that the proportion of citric acid have major influences on cineration of dried polymeric, the structure and component of LaNiO3. Uniformity nanoscaled LaNiO3 bar is got when the proportion of lanthanum nitrate, nickel nitrate and citric acid is between 1∶ 1∶ 0.6 and 1∶ 1∶ 0.7. Furthermore, the effect of sufficient or insufficient proportion of citric acid to the formation and cineration of sol-gel, to the purity of phases and spatial structures of LaNiO3 are discussed.关键词
