【摘要】 以乙酸镍和四氯化锡为金属源，葡萄糖为碳源，高纯水做溶剂合成前体，使用自制多孔阳极氧化铝(anodized aluminum oxide, AAO)作为硬模板，利用原位热还原合成Sn-Ni核壳纳米粒子(Sn-Ni-NPs)修饰一维碳纳米结构(Sn-Ni/C)复合材料。使用透射电镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)对样品进行检测和分析，结果表明，一维(1D)Sn-Ni/C纳米复合材料为具有中空管状结构，平均直径约为160 nm。核壳Sn-Ni-NPs均匀分布其管壁上。电化学研究是通过循环伏安法(CV)与安倍电流-时间法(I-t曲线)检测方法，探究了样品对葡萄糖的电催化性能，研究结果表明1D Sn-Ni/C纳米复合材料对葡萄糖有较高的电化学活性、良好的选择性、稳定性和重现性。更多还原

【Abstract】 Using nickel acetate and tin tetrachloride as metal sources, glucose as carbon source, high-purity water as solvent, the precursors were synthesized.The self-made porous anodized aluminum oxide(AAO)acted as hard template, the Sn-Ni core-shell nanoparticles(Sn-Ni-NPs)modified one-dimensional carbon nanostructure(Sn-Ni/C)composites were formed by in-situ thermal reduction.The samples were detected and analyzed by transmission electron microscopy(TEM),X-ray diffractometer(XRD),and X-ray photoelectron spectroscopy(XPS).The results reveal that the samples have the tubular structure with an average diameter of～160 nm, and Sn-Ni-NPs are uniformly distributed and highly dispersed in one-dimensional carbon nanostructures.Electrochemical catalytic performance of the sample on glucose was carried out by cyclic voltammetry(CV)and amperometric current-time method(I-t curve)techniques.The modified electrode obtain high electrochemical activity, good selectivity, stability and well reproducibility.更多还原
