摘　　要：采用化学气相沉积技术在铌基体上制备了BDD/Nb薄膜电极,并通过高温镍催化处理和电化学处理,获得了多孔BDD/Nb薄膜电极;选用活性橙X-GN染料废水进行了模拟降解实验,探讨2种电极降解废水效果。结果表明:相比于BDD/Nb电极,多孔BDD/Nb电极的有效电极面积增加了2.8倍;在活性橙X-GN染料废水降解实验中,多孔BDD/Nb电极的降解效率显著提高,相对于BDD/Nb电极,色度移除速度提高约4倍,COD移除速度提高约3倍,电流效率提高约15.92个百分点,能耗降低近75%。The porous Nb matrix boron-doped diamond(porous BDD/ Nb) membrane electrode was prepared by chemical vapor deposition technique based on Nb matrix boron-doped diamond(BDD/ Nb), followed by high-temperature nickel electrolysis and electrochemical treatment. Simulative degradation experiments were conducted using dye wastewater containing reactive orange X-GN(RO X-GN) for discussion of degradation effectiveness of two types of electrodes. Results showed that the effective electrode area of porous BDD/ Nb electrode was 2.8 times that of BDD/ Nb electrode. During the degradation experiment using RO X-GN, porous BDD/ Nb had a significantly increased efficiency, compared to BDD/ Nb electrode. The color removal rate of RO X-GN increased by about 4 times, the chemical oxygen demand removal rate was improved more than 3 times, the current efficiency was enhanced by 15.92 percentage points and the energy consumption was reduced by nearly 75%.
