Trace Amounts of Co(3)O(4) Nano-Particles Modified TiO(2) Nanorod Arrays for Boosted Photoelectrocatalytic Removal of Organic Pollutants in Water

Trace amounts of Co(3)O(4) modified TiO(2) nanorod arrays were successfully fabricated through the photochemical deposition method without adding any nocuous reagents. The Co(3)O(4)/TiO(2) nanorod arrays fabricated in acid solution had the highest photo-electrochemical activity. We elaborated on the...

description Trace amounts of Co(3)O(4) modified TiO(2) nanorod arrays were successfully fabricated through the photochemical deposition method without adding any nocuous reagents. The Co(3)O(4)/TiO(2) nanorod arrays fabricated in acid solution had the highest photo-electrochemical activity. We elaborated on the mechanism of Co(3)O(4)-TiO(2) fabricated in different pH value solutions. The Co(3)O(4)-TiO(2) had a more remarkable photo-electrochemical performance than the pure TiO(2) nanorod arrays owing to the heterojunction between Co(3)O(4) and TiO(2). The degradation of methylene blue and hydroquinone was selected as the model reactions to evaluate the photo-electrochemical performance of Co(3)O(4)-TiO(2) nanorod arrays. The Co(3)O(4)/TiO(2) nanorod arrays had great potential in waste water treatment.
