ABSTRACT
THE INFLUENCE OF SULFUR DOPING ADDITION TIME ON
EXTENSIVE SURFACE AND CRYSTAL NANOTITANIA
STRUCTURE USING SOL GEL METHOD
By
ANGGI PUSPITA DEWI
Synthesis of sulfur doping titania (S- TiO2) was carried out by the sol-gel method.
Titanium isopropoxide (TTIP), tween-80, isopropanol and asam sulfat (H2SO4) as
a source of sulfur doping are used as the of preccursor. This study aims to
determine the effect of sulfur doping for 0, 30, 60, 90 and 120 minutes using
injection pumps. Titania powder was calcined at 450 ℃ for 5 hours. S-doping
TiO2 was characterized using x-ray diffraction (XRD) and surface area analyzer
(SAA). The XRD results showed that the phase obtained was the anatase phase
for all samples while the results from the SAA showed that the S-02 sample
obtained a surface area the biggest is of 95,310 m2/g and the results of the
calculation of the particle size of the S-02 sample obtained a value of 10,17 nm.
The smaller the particle size obtained, the greater the surface area.
Keywords: Doping sulfur, SAA, titania, XRD.
