摘要
采用化学沉淀法制备了纳米Ni(OH)2,探索不同制备条件对Ni(OH)2堆积密度的影响.结果表明,所得试样为六方相类球形β-Ni(OH)2,堆积密度随体系pH值的增大和反应时间的延长,先增大后减小,当体系pH=11.5、反应时间6h时,Ni(OH)2堆积密度最大为0.85g/cm3;添加表明活性剂,不会影响Ni(OH)2晶形结构,但使试样的粒度减小,从而降低了堆积密度.
Nano-Ni（OH）2 was prepared by chemical precipitation method,Effect of Preparation Condition on bulk density of Ni（OH）2 was explored. The result showed that β-Ni（OH）2 was hexagonal. The bulk density begin to increase and then decrease with increasing the pH and reaction time,and has a maximum value at bulk density of 0.85 g/cm3. It was not change the structure of the crystal by doping surface active agent,The results indicate that descent of the particle size of Ni（OH）2 resulted in reduction of bulk density. Thus,in order to obtained high bulk density and electrochemical activity,the reaction condition must have a synthetic consideration.
