Abstract

Phosphated tin oxide-silica catalysts were synthesized by the sol-gel method using TEOS as silica source, CTAB as a surfactant, SnCl4.5H2O as precursor, and H3PO4 in water as a modifier, followed by thermal treatment of the mixture. The composite exhibit a high adsorption capacity of brilliant green (BG) as a cationic organic dye. The sample was systematically characterized by XRD, TEM, and FT-IR techniques.
