摘要
Ni(NO3 ) 2 ·6H2 O和NH4HCO3 在醇 水溶液中反应合成NiCO3 · 2Ni(OH) 2 ·2H2 O前驱体 ,经煅烧后得到大约 10nmNiO粉体。同传统的水溶液法相比 ,醇 水法得到的NiO粉体粒径尺寸小、分布范围窄和团聚少 。
Nanocrystalline nickel oxide (NiO) powder was prepared by thermal decomposition of the precursor of NiCO 3·2Ni(OH) 2·2H 2O obtained via Ni(NO 3) 2·6H 2O and NH 4HCO 3 reacting in alcohol water solution. Compared with water solution method, particle size of the NiO powder obtained by alcohol water method is smaller (～10nm) and its distribution is narrow. The addition of dispersant PEG can reduce powder agglomeration.
