【摘要】 采用NiCl2·6H2O和Na2C2O4为原料,在混合溶剂乙醇 水溶液中,通过化学沉淀法制备出一种浅绿色前驱物,以前驱物的热分析结果为依据,在400℃分解3h可得产物NiO粉体。经XRD、比表面积测定和TEM分析表明,产物为平均粒径23nm且粒径分布均匀、无团聚的球形纳米NiO粉体。更多还原

【Abstract】 NiO nanocrystallins materials were prepared by decomposing a light green precursor at 400℃. The precursor was obtained in alcoholwater mixed solvent by the reaction of NiCl2·6H2O and Na2C2O4. XRD, TG,DTA, determination of the specific surface area and TEM were used to characterize the obtained nanometer NiO powder. The results show that the NiO fine particles were nonagglomerated, spherical and well dispersed with the average size of 23nm.更多还原
