摘　　要：分别用氢气泡动态模板电沉积法和电势脉冲氧化还原法制备了三维微/纳米多孔铋薄膜和纳米多孔铋膜。利用扫描电子显微镜(SEM)和X射线粉末衍射(XRD)对其表面形貌和结构组成进行了表征。两种多孔铋膜对4-硝基酚的电还原有较高活性。Micro/ nano-porous bismuth films and nano-porous bismuth films have been prepared by electrodeposition with hydrogen bubble dynamic templates and by redox potential pulses, respective- ly. The morphology, structure and component of the two kinds of films were characterized by scan ning electron microscope （SEM） and X-ray diffraction （XRD）, respectively. These films demonstra ted high activity to the electrochemical reduction of 4-nitrophenol （4-NP）.
