| 摘要: 采用氢气泡动态模板电沉积法制备了三维多孔Au掺杂的Pd合金泡沫膜。采用场发射扫描电子显微镜（SEM）、能量分散X射线光谱仪（EDX）、X射线衍射（XRD）和X射线光电子能谱（XPS）对三维多孔PdAu合金泡沫膜的形貌和结构特征进行了表征。由于特殊的多孔结构和电子效应，Au掺杂的PdAu合金泡沫膜与单种多孔Pd膜相比，在碱性介质中对乙醇的电氧化具有高电催化活性。 |

| Abstract: Three-dimensional (3D) porous Au-doped PdAu alloy foam films were obtained by using a hydrogen bubble dynamic template electrodeposition method. The morphology and structure features of 3D porous Au-doped Pd alloy foam films were characterized by field-emission scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Due to the special porous structures and the electronic effects, the Au-doped PdAu alloy foam films showed high electrocatalytic activity toward the electrooxidation of ethanol in alkaline media as compared to pure porous Pd film. |
