SiO2 gels having a mesoporous morphology have been synthesized via a sol  gel processing route using rice husk as the starting material and further treated using additions of TiO2 from two sources. The chemical purity of  the SiO2 was measured by X-ray fluorescence analysis (XRF). Typical samples of pure TiO2, SiO2 and their composites were tested for surface characteristics using N2-sorption (BET surface area). All the different compositions processed have been characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and imaged using Scanning and Transmission Electron Microscopy (SEM, TEM). The UV absorption values which
