摘要

催化剂支撑层是由分散的纳米石墨薄片和镁离子组成的胶体在异丙醇中应用直流电泳沉积而成的。在电泳沉积EPD技术中，通过改变施加电压的时间来控制沉积层的厚度和电导率。催化剂支架由作为催化剂的溅射钯纳米结构装饰。制备的支持层具有最佳厚度，其电导率和电氧化性能得到改善，每mg钯可达到800 mA/cm2。

The influence of the thickness of nanographitic coatings fabricated by electrophoretic deposition on ethanol electro-oxidation

The catalyst support layer is fabricated by applying a DC electrophoretic deposition on a colloid consisting of dispersed nanographitic flakes along with magnesium ions in isopropyl alcohol. The thickness and conductivity of the deposited layers are controlled by varying the time of the voltage application in the electrophoretic deposition EPD technique. The catalyst supports are decorated by sputtering palladium nanostructures serving as the catalyst. The fabricated support layer with the optimum thickness exhibits an improved conductivity and electro-oxidation performance attaining 800 mA/cm2 per mg of palladium.
