Organic-inorganic hybrid materials formed by sequential vapor infiltration (SVI) of trimethylaluminum into polyester fibers are demonstrated, and the photoluminescence of the fibers is evaluated using a combined UV-vis and photoluminescence excitation (PLE) spectroscopy approach. The optical activity of the modified fibers depends on infiltration thermal processing conditions and is attributed ...

This work unravels a sudden deactivation of Pt/TiO2 (P25) during the initial stages of photocatalytic H2 evolution from aqueous solution that, until now, has gone unnoticed, using a unique combination of in situ photodeposition of Pt with an on-line gas detector system. Utilizing a set of techniques, including highresolution transmission electron microscopy (HRTEM), X-ray photoelectron spectros...

In this paper, we report a comparative study on the methods (chemical reduction and photo-assisted deposition) of incorporating Pt onto TiO2 nanoparticles (TNP) for H2 generation. The phase structure photocatalysts was scrutinized utilizing TEM XRD. degree dispersion TNP is measured by pulse chemisorption technique, using TPDRO equipment. Results provided images, EDX spectra, elemental mapping,...
