以六水合氯化钴、六水合氯化镍和六次甲基四胺为原料,通过引入乙醇溶剂,利用醇-水热法合成钴镍双金属氢氧化物。采用扫描电子显微镜、电化学工作站等对所制材料的形貌及电化学性能进行表征。从扫描电子显微镜可以看出,利用醇-水热法合成的钴镍双金属氢氧化物具有较薄的片状结构;电化学测试结果表明合成的双金属氢氧化物具有较优异的电化学性能,在电流密度为1A/g时,其比电容达到586.7F/g。
Co-Ni layered double hydroxides were synthesized via solvo-thermal method using cobalt chloride and nickel chloride as cobalt and nickel sources with hexamethylenetetramine as the precipitant and ethanol as the template.The morphology of the samples was characterized by scanning electron microscopy and the electrochemical properties were performed by electrochemical workstation.The results indicated that Co-Ni layered double hydroxides had thinner sheet structure and more excellent electrochemical properties with a specific capacitance 586.7F/g under a current density of 1A/g.
