[Photoelectrocatalytic degradation of Rhodamine B using mesh Ti/TiO2 electrode]

An innovative mesh titanium dioxide (TiO2) electrode was prepared by anodisation. The morphology and the crystalline texture of the TiO2 film on electrode were examined by SEM and Raman spectroscopy respectively. The results indicated that the structure and properties of the film depended on anodisation rate, and the anatase was the dominant component under the controlled experimental conditions. Biasing could increase the efficiency of photocatalytic degradation of organic matters. Mineralization Rhodamine B (Rh B) was complete relatively in photoelectro-catalytic (PEC) oxidation. Both chromogen destruction of Rh B and de-ehtylation in PEC degradation took place simultaneously.
