	abstract = {MCM-48 cubic mesoporous materials contg. CdS and spatially isolated titania nanoclusters were prepd. in this study.  Powder X-ray diffraction (XRD), nitrogen adsorption isotherm, transmission electron microscopy (TEM), at. absorption spectrophotometry (AAS), UV-Visible diffuse reflectance spectroscopy (DRS), XPS, and ESR (EPR) studies were employed for the characterization of the CdS contg. Ti-MCM-48 mesoporous materials.  In the current study, all the samples showed photocatalytic activity under visible light (λ > 400 nm) irradn. for prodn. of hydrogen from splitting of water without Pt as a co-catalyst.  The solar hydrogen evolution rate by visible light irradn. seemed to be dependent on CdS and TiO2 content and the most active photocatalyst produced hydrogen at a rate of 2.726 mmol/h/gcatalyst.  The apparent quantum yield of the most active photocatalyst was estd. to be 36.3\%. [on SciFinder(R)]},

	abstract = {Cobalt-contg. TiO2 mesoporous materials were prepd. by Evapn.-Induced Self-Assembly (EISA) process.  The resulting mesoporous materials were characterized using powder X-ray diffraction (XRD), nitrogen physisorption, Raman spectroscopy, diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), XPS, and photoluminescence spectroscopy (PL).  The photocatalytic activities of the mesoporous materials were investigated for hydrogen prodn. under solar simulated conditions.  The non-modified TiO2 sample produced only 4 μmole H2/g catalyst after 4 h of irradn.  In contrast, the Co contg. mesoporous materials produced significantly higher amts. of hydrogen under identical conditions.  The highest solar hydrogen evolution (634 μmole H2/g catalyst after 4 h of irradn.) was from the Co-TiO2-0.5 material.  The physico-chem. characterization results indicate that the Co2+ ions are dispersed as oxide species on the surface of the mesoporous titania.  These cobalt surface species act as trap sites preventing recombination of the charge carriers as shown by PL measurements.  The addn. of Co2+ ions to the synthesis mixt. prevents the formation of anatase-to-rutile which favorably permits more solar hydrogen prodn. [on SciFinder(R)]},

	abstract = {We report a facile method for the synthesis of 4-mercaptobenzoic acid (MBA) stabilized CdS-trititanate nanotube (CdS-TNT) composite materials.  The resultant materials were well characterized by powder X-Ray Diffraction (XRD), N2 physisorption, Raman spectroscopy, UV-Visible Diffuse Reflectance spectroscopy (DRS), Fourier-Transform Infra-Red (FT-IR) spectroscopy, Photoluminescence (PL) spectroscopy, XPS, Atomic Absorption Spectroscopy (AAS), and Transmission Electron Microscopy (TEM).  The photocatalytic performances of these materials were evaluated by monitoring the amt. of hydrogen evolved from water under visible light irradn.  The amt. of hydrogen evolved from MBA stabilized CdS-TNT composite materials were higher compared to MBA stabilized CdS, suggesting an important role of the TNT support.  The enhanced photocatalytic hydrogen generation in MBA stabilized CdS-TNT composite materials compared to CdS-MBA might have arisen from the effective charge sepn. in CdS-TNT composite materials, which was further supported by PL studies.

	abstract = {Platinized TiO2 photocatalysts of different compns. of Pt0 and PtO2 were prepd. by modifying the synthesis procedures.  The physicochem. properties of the composite materials were characterized by XPS and high-resoln. transmission electron microscopy.  Energy dispersive X-ray spectroscopy measurements confirmed the presence of Pt species existing as PtO2 and/or mixts. of Pt0 and PtO2.  The composite material, Pt-TiO2-2\%H, contained a high amt. of metallic Pt0 and PtO2 in close proximity with TiO2 that promoted an enhanced photocatalytic hydrogen evolution activity under simulated solar light irradn.  Although Pt-TiO2-2\%C and Pt-TiO2-2\%T consisted of similar compns. of PtO2, these oxidized platinum species seem to appear further apart from TiO2 in Pt-TiO2-2\%C than Pt-TiO2-2\%T.  This caused dramatic variation in their optical behaviors such as strong fluorescence quenching and lower photocatalytic hydrogen evolution activity in the former photocatalyst.  A photocatalyst prepd. by the conventional photodeposition method was also prepd., characterized, and its photocatalytic activity assessed.  This work provides an opportunity to understand the role of PtO2 for photocatalytic prodn. of hydrogen from platinized TiO2 composites and the importance of heterojunctions in such photocatalysts for solar energy conversion.
