中文摘要：
采用水热法在不同水热温度下合成了氧化镍。利用X射线衍射仪（xRJ））、扫描电子显微镜（SEM）对产品进行了表征。获得制备氧化镍的最佳水热温度为85℃，该温度下产物为具有二级结构的球状颗粒，平均粒径3－4nm，二级片状结构的平均厚度为70－80m。然后电沉积铂获得Pt-NiO／C，利用循环伏安法探索不同铂含量的复合材料对乙醇的电催化性能。结果表明，沉积40次时Pt-NiO／C的电催化性能最佳。
英文摘要：
NiO was prepared by hydrothermal method under different reaction temperature. The crystallinity and morphology of the powders were characterized by X-ray diffraction （XRD） and scanning electron microscope （SEM）. The optimal temperature was 85 ℃. The NiO obtained was particles with a diameter of 3-4 pm which consisted of nanoslices with the thickness of about 70-80 nm. Pt was electrodeposited to synthesis Pt-NiO/C composite catalyst. The electrochemical activity of Pt-NiO/C for ethanol oxidation was investigated under different conditions by cyclic voltammetry （CV） method. The results show that the best catalytic activity of composite for ethanol electrooxidation is obtained when the scanning segments of electrodeposition of Pt is 40 times.
