Abstract
Ti-MCM-41 were synthesised by one-step method using sodium silicate extracted from iron ore tailing as silicon source, tetrabutyl titanate as titanium source and cetyltrimethylammonium bromide as the template. The effects of various experimental parameters, such as molar ratio of Si/Ti, reaction temperature and time, were investigated. The as-synthesised samples were further characterised by X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning electron micrographs, N2 absorption–desorption and transmission electron microscopy techniques. The results indicated that Ti-MCM-41 materials possessed the ordered hexagonal mesostructure and high surface area.
