摘要
Abstract
The anatase type TiO2 nanotubes were prepared on Ti surface by electrchemical anodic oxidation method. Using the TiO2 nanotube membrane as anode, the factors affecting photoelectrocatalytic degradation of acid orange were studied. The experimental results show that: Under the optimum conditions of solution pH 3.0, external bias potential 2.5 V, NaCl concentration 0.05 mol/L and reaction time 30 min, the acid orange degradation rate can reach 99.99%; After the TiO2 nanotubes is reused for 25 times, the acid orange degradation acid orange degradation rate can still reach 94.57%.关键词
