摘　　要：本文通过液相法获得钯金/碳壳纳米复合材料,使用TEM,EDX和XPS等表征手段对其形貌及化学组成进行分析,并将该纳米复合材料用作电催化剂,考察其对乙二醇和丙三醇等有机小分子的电催化氧化性能.结果表明:该纳米复合材料对乙二醇和丙三醇等有机小分子具有较好的电催化活性和稳定性.In this paper, palladium-gold/carbon shell nanocomposite is obtained by liquid phase method. The morphology and chemical composition are analyzed by characterization techniques such as TEM, EDX and XPS. The electrocatalytic performance towards the oxidation of organic molecules like ethylene glycol and glycerol is also examined. Results show that the nanocomposite with bimetallic nanoparticle outside the nanoshell exhibits better electrocatalytic performance towards the oxidation of alcohol.
