Abstract
The synthesis of nanotitania was prepared using the sol gel method with the addition of ethanolamine as a surfatan. This research was conducted to determine the effect of ethanolamine addition on the photocatalyst activity and energy gap of nanotitania. In this study, the use of titanium butoxide acts as a precursor, ethanol as a solvent and HCl as a converter for sol to gel. The addition of varied ethanolamine is 0; 0.5; 1; 1.5; and 2 ml. The sample was calcined at 500ºC for 4 hours. Nanotitania were characterized using Raman Spectroscopy, UV-Vis Spectrophotometry, and UV-Visible Diffuse Reflectance Spectroscopy (UV-Vis DRS) using the Kubelka-Munk method. The results of the characterization of Raman spectroscopy showed that the C-1 sample formed anatase, rutile and brookite phases. Test the photocatalyst activity by degrading remazole yellow solution using sunlight as the trigger. The results of the UV-Vis DRS characterization of the energy gap of each samples are 3.18; 3.2; 3.03; 3.15 and 3.2 eV for samples of A-0, B-0.5, C-1, D-1.5 and E-2 respectivly. Keywords - Energy gap, Ethanolamine, Nanotitania, Photocatalyst, Remazol Yellow.
