Self-cleaning Kaca Berbasis Lapis Tipis TiO2 dengan Perlakuan Asam dan Asam Palmitat sebagai Model Polutan
ABSTRACT: Preparation and
characterization of self-cleaning glass based on acid-treated TiO2 films as
well as evaluation on their self-cleaning properties have been carried out.
Palmitic acid photodegradation was used as model pollutant. Acid-treated TiO2
powders were deposited on glass surface by using spraying technique. The XRD
results showed that acid-treated TiO2 film exhibited decreased anatase
crystalline size. The corresponding SEM images showed porous surface
morphology. Layer densification was observed as the film thickness increased.
TiO2 photocatalytic activity increased as the length of UV radiation increased.
Best results were obtained at experimental condition of 35 hours UV radiation
time. It is also observed that the thickness of TiO2 layers influenced the
efficiency of palmitic acid photodegradation. The film with 1.661 µm thick TiO2
layers and 6.933 mg weight (0.7164 mg/cm2) could degrade 97.54 % mg palmitic
acid/cm2 thin film.
