Abstract

Nanotitania has been prepared by sol gel method using ethanolamine as surfactant. This research was conducted to determine the effect of ethanolamine on the phase formation, particle size and surface area of TiO2. In this study Ti-butoxide was used as a precursor and ethanol as a solvent, and then HCl. The amount of ethanolamine was varied to 0; 0.5; 1; 1.5; and 2 ml. The samples were calcined at a temperature of 500ºC for 4 hours. TiO2 was characterized using X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), and Surface Area Analyzer (SAA) with BET method. The results of XRD characterization showed that in samples A-0.0 and A-0.5 an anatase phase was formed, whereas in the sample A-1,0 and A-1,5 an anatase, brookite, and rutile phases were formed with a weight percentage of 57,65 ± 1,6% wt; 27,06 ± 1,8% wt, and 15,29 ± 0,4% wt. Meanwhile, for sample A-1,5  it is 69,96 ± 1.6% wt, 24,52 ± 1,5% wt, and 5,52 ± 0,3% wt. Sample A-2.0 only produced anatase and brookite phases with weight percentages of 78,53 ± 1.5% wt and 21,47 ± 1.5% wt. The results of TEM characterization using ImageJ software show that the TiO2 particle size in sample A-1,0 was 15,8 ± 1,0 nm. The results of the analysis surface area of sample A-1, produced the largest specific surface area, that is 172 m2/g, the smallest specific surface area was produced in sample A-1,5  that is 72,07 m2/g.
