Abstract
In this work, titanium dioxide (TiO2) photocatalyst was generally immobilized onto glass plate support material by employing double sided adhesive tape (DSAT) as a thin layer binder. The photocatalytic performance of this new non-additive immobilization system was observed under the degradation of two different charges of dyes namely anionic reactive red 4 (RR4) and cationic methylene blue (MB) dyes. Photocatalytic degradation of RR4 and MB dyes under immobilized TiO2/DSAT were compared with TiO2 in suspension mode respectively. Immobilized TiO2/DSAT was observed to have up to 30 cycles of reusability thanks to DSAT that is able to provide a very strong intact between the glass plate and TiO2 layers. In fact, a better photodegradation activity was observed by number of photocatalysis cycles due to increasing pores formation on TiO2 surface as observed by Scanning Electron Microscopy (SEM) analysis.
