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8 h，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276 m2/g和0.248 cm3/g；对葡萄糖氧化有良好的电催化作用。

Abstract:

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 m2/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.

Key words: carbon doped, Ni microsphere, hydrothermal method, glucose, electrocatalytic oxidation
