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。
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.
