碳基片上沉积的金刚石涂层多孔电极的特性OA北大核心CSCDCSTPCD
Characterization of Diamond Electrode Deposited on a Porous Active Carbon Pellet
采用化学气相沉积法(CVD)在多孔活性碳基体上制备掺硼金刚石涂层多孔电极.用扫描电子显微镜(SEM)法表征了金刚石膜的表面微观结构,采用循环伏安法和交流阻抗法研究了电极的电化学性质.结果表明,金刚石表面形态为球形,金刚石膜电极具有很宽的电势窗口,在酸性、中性和碱性3种介质中分别为4.4V、4.0V和3.0V.在铁氰化钾电解液中,金刚石膜电极表面在反应过程中始终保持良好的活性,在表面进行的电化学反应具有良好的准可逆性.
Active carbon pellet as substrates for the deposition of diamond films were prepared by chemical vapor deposition (CVD). The ballas diamond morphologies of the as-deposition films were analyzed by scanning electron microscopy. Raman spectroscopy was used to investigate the crystal structure. The electrochemical behavior of a boron-doped diamond film electrode prepared on porous active carbon substrates was studied by cyclic voltammetry and AC Impedance. The …查看全部>>
