	abstract = {A cubic MCM-48 mesoporous material was employed as a support to encapsulate earth abundant NixOy species (NiO and Ni2O3).  The cubic MCM-48 mesoporous support provides an excellent platform to not only effectively disperse NiO and/or Ni2O3 species but also to limit their particle sizes.  The presence of Ni2O3 species at an optimal amt. seems to enhance the photocatalytic activity of Ni-MCM-48 materials in comparison to a Ni-MCM-48 mesoporous material having only NiO dispersed in it.  In addn., the presence of bulk NiO species also seems to be detrimental to the generation of solar hydrogen.  The apparent quantum yield (AQY) of the most active material, Ni-MCM-48-2.5\% was estd. to be 5.35\%.  This was over 250 times higher than a bulk, NiO (AQY = 0.02\%) under identical exptl. conditions.  This study indicates that MCM-48 can be used as an effective support to disperse NixOy species.

	abstract = {We report a green and facile approach for the prepn. of carbon-modified (C-modified) TiO2 composite materials by hydrothermal synthesis followed by pyrolytic treatment.  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.
