Abstract
Ti, Zr and Hf ions have been incorporated into mesoporous silica using a no vel one-pot procedure based on the true liquid crystal templating (TLCT) sy nthesis method. The nature of the metallic sites was assessed using diffuse reflectance UV-visible, photoluminescence and FT-IR spectroscopy. In situ adsorption of oxygen and ammonia probe molecules provided information on th e accessibility of optically active species.
