Abstract:
Titanium dioxide thin film was synthesized by hydrolysis and condensation process by sol-gel method in this research. Titanium (VI) butoxide was used as initial substrate and ethanol was used as solvent. Diethanolamine was studied as organic additive in this research. This study was aimed to investigate effect of diethanolamine on TiO, thin film properties which are adherence and corrosive properties, TiO, molecular structure, and surface morphology of thin film. Molar ratio of TiO, to diethanolamine, calcinations temperature, and coating cycles were varied as studied parameter. It was found that diethanolamine enhanced the adherence property and provided the smooth surface of TiO, thin film. The calcinations temperature at 600?C provided the highest photoactivity of thin film as examination by chromium (VI) photocatalytic removal test. The 5 coating cycles yielded the highest of anatase peak resulting highest performance in chromium removal. Findings from this research provide the fundamental knowledge in TiO, thin film synthesis and can be applied to future research for commercial scale.
