| 摘 要： | 应用恒电位沉积(psd)和电位脉冲沉积(ppd)法在Pt基底制备CeO2/Pt复合电极,用能量色散X射线光谱(EDX)和X射线衍射(XRD)检测CeO2纳米粒子的成分和结构,场发射扫描电子显微镜(FESEM)观察样品形貌.结果表明:CeO2颗粒细小、致密.在KOH溶液中,CeO2/Pt对甲醇氧化和氧还原有电催化作用;若在稀硫酸中溶除CeO2/Pt电极(ppd)的部分CeO2,则电极的电催化作用进一步增强.

| Abstract: | In this paper,the cerium oxide(CeO2) nanoparticles were electrochemically deposited on a Pt electrode by potentiostatic deposition(psd) and potential pulse deposition(ppd) to form CeO2/Pt composite electrodes,CeO2/Pt(psd) and CeO2/Pt(ppd).The properties of the CeO2 were characterized by field emission scanning electron microscope(FESEM) and X-ray diffraction(XRD).The results showed that the CeO2 nanoparticles prepared by psd and ppd were homogeneous and dense.The methanol oxidation reaction(MOR) and oxygen ... |
