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 ,PEG的添加能够减少团聚
Ni (NO3) 2 · 6H2O and NH4HCO3 in aqueous alcohol to synthesize NiCO3 · 2Ni (OH) 2 · 2H2O precursor, calcined to obtain about 10nmNiO powder. Compared with the traditional aqueous solution method, the NiO powder obtained by the alcohol-water method has the advantages of small particle size, narrow distribution range and less agglomeration, and the addition of PEG can reduce agglomeration
