제목 Rapid Synthetic method of Titania-silica systems with improved photochemical properties
초록 The textural properties of TiO2-SiO2 composites (TSCs) were successively enhanced using three approaches; (1) washing the hydrogels with different solvents, (2) using surfactant and (3) forming the TiO2 sol in ethanol medium. The sol-gel process was exquisitely used to form the composites using cost effective precursors. Initially, the precipitated hydrogels were washed with water or alcohol to evaluate the influence of washing on the dried hydrogels. Consequently, two composites were formed differently in the presence of stearic acid (SA) as a surfactant and the other by forming TiO2 sol in ethanol medium prior to reaction with silica source. Photocatalytic decolorization of methylene blue by the composites calcined at 800℃ revealed that the TSCES-800 possessed the highest activity of all the composites due to its superior properties
