Effects of Layers and Ratio Cs-TiO2/Glass Photocatalyst towards Removal of Methylene Orange via Adsorption-photodegradation Process

View Abstract and References

Preparation of Cs-TiO2 films by using glass substrate with synthesized TiO2 and the study of photocatalytic activity of Cs-TiO2 in the removal of methyl orange (MO) under  the optimum conditions was conducted. Initially, TiO2 nanoparticles was synthesized via sol gel methods and its chemical, physical and photocatalytic  properties were characterized accordingly. This was divided into two parts which involved the as-synthesized sample (before calcination) — undergoing thermo-gravimetric analysis and then the same synthesized sample underwent Fourier transform infrared spectroscopy, X-ray diffraction and Raman spectroscopy analyses after it was calcined. Then, TiO2 was incorporated with Cs solution in acidic medium before immobilized on glass substrate. UV-vis analysis was done to study the adsorption–photodegradation analysis of MO. It demonstrated that, the combination effects on adsorption–photodegradation process for the removal of MO occur promisingly when eight layers at 3:2 weight ratio (TiO2:Cs) of Cs-TiO2/glass photocatalyst was used for MO photodegradation. Approximately, 70% to 85% of total MO degradation by photocatalyst analysis was achieved. Therefore, a suitable photocatalytic conditions and sample parameters, possessing the Cs-TiO2 gave  the benefits of adsorption–photodegradation practice in the abatement of wastewater contaminants.
