摘　　要：以葡萄糖酸钠与硝酸镍为起始原料,通过水热合成法,制备了碳杂Ni(OH)2复合微球(C-Ni(OH)2),Ni2+的沉淀剂OH-是由葡萄糖酸钠水解提供的;以制得的C-Ni(OH)2微球为前驱体,在N2气氛围中下焙烧8h,制得了碳杂金属镍(C-Ni)微球,通过场发射扫描电子显微镜(FE-SEM)、X射线衍射(XRD)、X射线能谱(EDS)和N2气吸附脱附实验等测试技术对其进行了分析,结果表明,C-Ni微球具有较大的比表面积和孔容,分别为276m2/g和0.248cm3/g;对葡萄糖氧化有良好的电催化作用。Ni（OH）2 doped with carbon（C-Ni（OH）2） microsphere was prepared by the hydrothermal method via starting with sodium gluconate and nitrate nickel.The precipitant OH-comes from the hydrolysis of sodium gluconate＇s carboxylic acid.The as-prepared C-Ni（OH） 2 microsphere was adopted as the precursor for fabricating Ni doped with carbon（C-Ni） microsphere by calcined 8 h at 600 ℃ in N2,and the resulting C-Ni microsphere was further characterized by FE-SEM,XRD,EDS,and BET,verifying the C-Ni microsphere possess considerable large surface area and pore volume of about 276 m^2/g and 0.248 cm3/g,respectively.Finally,the electrochemical experiment showed that C-Ni microsphere exhibited good electrocatalytic activity toward the oxidation of glucose.
