摘要
以NiSO_4·6H_2O为原料,尿素为沉淀剂,聚乙烯吡咯烷酮(PVP)为分散剂,在130℃的温度下,通过乙二醇—水体系制得Ni(OH)_2微球。XRD物相分析表明所得产物为α-Ni(OH)_2,SEM表明产物是由片状Ni(OH)_2构成的具有层次结构的微球,微球直径约1μm,呈现较好的分散性。用循环伏安法测试α-Ni(OH)_2的电化学性能发现:产物具有一定的电化学氧化还原性。
Ni（OH）2 microspheres were synthesized by refluxing glycol-H2O solution of NiSO4 and urea at 130℃. The samples were characterized by XRD and SEM. It has been found that the as-synthesized sample was α-Ni（OH）2. The SEM observation results indicated that Ni（OH）2 microspheres were constructed with Ni（OH）2 nanosheets, showing hierarchical structures. The electrochemical property of the sample was obtained through cyclic voltammetry method, which showed redox performance.
