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。

The surface morphology and crystal structure of three-dimensional 3 D-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.
