The chromium ion loading and the effect of counterion in the synthesis were studied.  The mesoporous materials were extensively characterized by powder XRD, N2 physisorption, Atomic Absorption Spectroscopy (AAS), FTIR Spectroscopy (FTIR), Diffuse Reflectance Spectroscopy (DRS UV-visible), hydrogen Temp.-Programmed Redn. (H2-TPR), XPS, and TEM studies.  A transition from Ia3̅d cubic phase to p6mm hexagonal or wormhole phases was noted as more amts. of chromium were incorporated into the siliceous materials.  Chromium species present in the silica matrix include monochromate, polychromate, and chromium oxide (Cr2O3) clusters.

The resultant materials were characterized by powder X-ray diffraction (XRD), nitrogen physisorption studies, Raman spectroscopy, XPS, diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy, and transmission electron microscopy (TEM).  The photocatalytic performances of these materials were evaluated by calcg. the amt. of hydrogen evolved from the decompn. of water under solar simulated irradn. conditions.  An improvement was achieved from no H2 evolution at all with the bare TiO2, to an evolution of 0.21 mL g-1 h-1 from a composite material modified with an optimum carbon loading of 3.62%.  These results suggested that the interaction of carbon with predominantly rutile form of TiO2 can promote shallow trapping of photogenerated electrons in the oxygen vacancies.  This phenomenon consequently enhances the photocatalytic activity by minimizing charge carrier recombination, a characteristic demonstrated by fluorescence quenching of the TiO2 emission.
