Abstract

Abstract. F-doped TiO2 has been synthesized using the sol-gel method using NH4F as a source of fluorine. This study aims to determine the effect of adding variations in the rate of doping fluorine during 0, 30, 60, 90 and 120 minutes using an injection pump to the formation and change of crystal structure and specific surface area of TiO2. Titanium isopropoxide (TTIP), tween-80, isopropyl alcohol and NH4F are used as the main ingredients in the synthesis of nanotitania. The F-TiO2 powder was then calcined at 450 °C for 5 hours. The powder was tested for characterization using x-ray diffraction (XRD) and surface area analyzer (SAA). The XRD characterization results showed that all samples had purely anatase phases. XRD analysis on sample F-01 with a drop rate of 0 minutes obtained the largest particle diameter of 14.21 nm. Whereas the sample F-04 with a dropping rate of 90 minutes obtained the smallest particle diameter of 11.60 nm. The results of the SAA characterization in sample F-01 with a drop rate of 0 minutes obtained the smallest surface area of 68.845 m2 /g. Whereas in sample F-04 with a dropping rate of 90 minutes the largest surface area was 103,585 m2 /g. Keywords: fluor-doped, SAA, TiO2, XRD.
