Methyl Orange Photoelectrocatalytic Degradation Using Porous TiO2 Film Electrode in NaH2PO4 Solution

摘要：

Porous TiO2 film was prepared by a sol-gel method using PEG1000 as pore forming template．The porous film and normal film were used as electrodes in a photoelectrocatalvtic reactor．The functions of applied potential and concentration of NaH2PO4 to the photoelectrocatalytic degradation process of methyl orange were investigated．The results show that methyl orange cannot be degraded solely by the applied potential． Under the applied potential of 2 V．49.9％of the initial dye can be removed on the normal Ti02 film electrode， which．is much better than the 31.1％removal rate on the porous TiO2 film electrode．The normal TiO2 film electrode has better performance than the porous TiO2 film in the whole NaH2PO4 concentration range．After 80 min of reaction,degradation rate is 93.7％on the normal TiO2 film electrode．After 100 min of reaction,degradation rate is 89.7％on the porous TiO2 film electrode．
