中文摘要：

利用扫描电子显微镜（SEM）和X射线衍射仪（XRD）对多孔Ti/BDD电极及传统平板Ti/BDD（BDD=钛基掺硼金刚石）电极进行了研究,通过循环伏安法考察了电极的背景电流和电化学窗口.以阿司匹林为模型污染物,研究了BDD电极结构对阿司匹林电催化降解的影响.结果表明,多孔Ti/BDD电极的总带电量,内、外部带电量,孔隙率和比表面积均高于平板Ti/BDD电极;多孔Ti/BDD在对COD和阿司匹林的去除率和能量消耗等方面均优于平板Ti/BDD电极.

英文摘要：

The surface morphology and crystal structure of three-dimensional 3D-porous titanium / boron-doped diamond（ porous Ti / BDD） and planar Ti / BDD electrodes were studied by scanning electron microscopy（ SEM） and X-ray diffraction（ XRD）. The cyclic voltammetry measurements of porous Ti/BDD and planar Ti / BDD electrodes were also performed. Porous Ti / BDD and planar Ti / BDD electrodes were used as anodes in the degradation of Aspirin,respectively. The results indicate that porous Ti / BDD has larger total,outer,and inner charges,porosity,and actual surface area due to the porous structure. Compared to planar Ti / PDD,porous Ti / BDD electrode is better on removal rate of chemical oxygen demand（ COD） and Aspirin and energy consumption.
