Ti, Zr and Hf ions have been incorporated into mesoporous silica using a novel one-pot procedure based on the true liquid crystal templating (TLCT) synthesis 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 the accessibility of optically...
Studies on powders are of great interest in all fields of materials science. For fundamental research, it is relevant to determine the structure of solids at the ''boundary'' with the external environment where relaxation, reconstruction, adsorption and related phenomena occur. In the case of technological research, application for catalysis, pigments, etc., detailed information are required on morphology...
