THE EFFECT OF CALCINATION TEMPERATURE TO THE COMPOSITE CHARACTERISTICS OF TiO2SiO2 NANOPARTICLE

THE EFFECT OF CALCINATION TEMPERATURE TO COMPOSITECHARACTERISTICS TiO2SiO2 NANOPARTICLE. Self-cleaning material is a that utilizes the photocatalytic property to degrade organic and inorganic compounds with help of UV light. One materials have good TiO2, causes TiO2 be amphiphilic: becomes hydrophilic when there light hydrophobic no The can improved addition buffer such as SiO2. nanoparticle was synthesized using sol-gel method Titanium (IV) Isopropoxide (TTIP) precursors for Tetraethyl Orthosilicate (TEOS) SiO2 followed by variation calcination temperature 400 °C, 450 500 550 °C 2 hours. composite composition sol 75% 25%. result synthesis characterized Fourier Transform Infra-Red (FT-IR) instrument determine functional groups in composites X-Ray Diffraction (XRD) instruments phase, crystallite size degree crystallinity composite. purpose this research self cleaning agent temperature, obtain characteristics support cleaning. self-cleaning ability based on produced characteristic TiO2SiO2. FTIR characterization showed at Ti-OSi bond peak 948.91 cm-1, 950.77 941.13 942.13 cm-1. XRD had best characteristics, 75.27% anatase phase brookite 24.72%. Calcinations 91.66%.
