| 摘 要： | 在乙二醇体系中,制备出了具有两种孔径结构的Co3O4空心球,然后以Co3O4空心球作为载体,以葡萄糖作为还原剂,还原H2PtC l6.6H2O可以将Pt颗粒沉积在空心球表面。利用X射线粉末衍射(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM)和能谱分析(EDS)等手段对产物进行了表征。在常温条件下,用CV曲线(Cyclic voltam-m etry)在H2SO4/CH3OH溶液中测试Pt/Co3O4的电化学性质。结果显示:Pt/Co3O4修饰电极能提高Pt的利用率因而具有增强甲醇氧化作用的效果。

| Abstract: | Co3O4 hollow microspheres with two kinds of pore structures are produced in ethylene glycol system and are subsequently deposited with Pt particles by a simple liquid reduction method with chloroplatinic acid as the Pt source and glucose as the reducing agent.The products are characterized by powder X-ray diffraction(XRD),transmission electron microscopy(TEM),scanning electron microscopy(SEM) and the energy-dispersive spectrometry(EDS).The electrocatalytical activity of Co3O4 with Pt loadings is analyzed by... |
