以十二烷基硫酸钠为模板剂,采用尿素为沉淀剂,用均匀沉淀法,适当控制尿素的水解速度,制备具有介孔结构的氢氧化镍胶体,在不同温度下焙烧处理得到孔分布集中的氧化镍介孔分子筛.结果表明,在523K下焙烧得到的氧化镍BET比表面达到477.7m~2·g~(-1).结构表征还显示,介孔氧化镍的孔壁为多晶结构,其孔结构形成机理应为准反胶束模板机理.循环伏安法表明用NiO介孔分子筛制备的电极有很好的电容性能.与浸渍法和阴极沉淀法制得的NiO相比,这种介孔结构的NiO能够大量用来制作电化学电容器电极,并且保持较高的比电容量和良好的电容性能. Using sodium dodecyl sulfate as templating agent and urea as precipitating agent, uniform precipitation method was adopted to properly control the hydrolysis rate of urea to prepare nickel hydroxide colloid with mesoporous structure. The pore distribution was concentrated by calcination at different temperatures Of nickel oxide mesoporous molecular sieve.The results showed that the BET specific surface area of ​​nickel oxide calcined at 523K reached 477.7m 2 · g -1 .The structural characterization also showed that the pore wall of mesoporous nickel oxide was polycrystalline , The formation mechanism of the pore structure should be quasi-reverse micelle template mechanism. Cyclic voltammetry shows that the electrode prepared with NiO mesoporous molecular sieve has good capacitance properties. Compared with the impregnation method and cathode precipitation of NiO, this NiO mesoporous structure can be used to make a large number of electrochemical capacitor electrode, and to maintain a high specific capacitance and good capacitance performance.
