Pengaruh Laju Penginjeksian Doping Sulfur terhadap Aktivitas Fotokatalis Nanotitania Menggunakan Metode Sol Gel
Abstract. Synthesis of sulfur doped titania (S-TiO2) was carried out through sol-gel method. Titanium isopropoxide (TTIP), tween-80, isopropanol and sulfuric acid (H2SO4) as a source of sulfur doping were used as raw material. The aimed of this research is to study the effect of the rate of sulfur doping injection by using an injection pump toward S-TiO2 photocatalyst activity. Four sulfur doping samples were prepared with rate injection of 4 ml/30; 4 ml/60; 4 ml/90 and 4 ml/120 minutes respectively. Titania powder was calcined at temperatur of 450 oC for 5 hours. The sintered samples were tested for photodegradation of remazol yellow under UV irradiation. Physical characteristics were analyzed using transmission electron microscopy (TEM) and UV-Vis Spectrophotometer. The result of the UV-Vis spectrophotometer showed that sample with an injection rate of 4 ml/30 minutes showed higer photocatalyst activity with the particle size is (7,1 nm ± 1,9 nm)
