Core-shell NiO/CMs used as the support of Pt for electocatalytic oxidation of methanol

采用水热法制备碳微球作为催化剂材料的核,同时在碳微球表面通过水热合成一层NiO的壳,形成核壳结构的NiO/CMs。通过电化学沉积法在核壳结构的NiO/CMs表面沉积铂颗粒,形成Pt/NiO/CMs复合体,作为新型甲醇燃料电池的催化电极。通过扫描电子显微镜(SEM)对核壳结构的NiO/CMs的表面形貌进行了表征,并采用电化学方法研究了Pt/NiO/CMs复合体电催化氧化甲醇的性能。

Carbon microspheres （CMs）, as the core of the catalyst material, were prepared by hydrothermal method, and a layer of NiO shell was synthesized by hydrothermal synthesis on the surface of CMs to form core - shell NiO/CMS. The Pt/NiO/CMs complex was formed by electrochemical deposition in the core - shell NiO/CMs surface, as a catalytic electrode for the novel methanol fuel cell. The surface morphology of core - shell NiO/CMs was characterized by scanning electron microscope （ SEM ）. The performance of the Pt/ NiO/CMs complex for electro - catalytic oxidation methanol was studied by electrochemical method.
