Au Modified F-TiO2 for Efficient Photocatalytic Synthesis of Hydrogen Peroxide

Direct evidence of plasmon enhancement on photocatalytic hydrogen generation over Au/Pt-decorated TiO2 nanofibers.

Direct evidence of plasmon-enhanced H2 generation is observed in photocatalytic water reduction by using TiO2 electrospun nanofibers co-decorated with Au and Pt nanoparticles through dual-beam irradiation. The Au/Pt/TiO2 nanofibers exhibit certain activity for H2 generation under single irradiation at 420 nm that excites the defect/impurity states of TiO2. Significantly, when secondary irradiat...

Carbon-Modified Mesoporous Anatase/TiO2(B) Whisker for Enhanced Activity in Direct Synthesis of Hydrogen Peroxide by Palladium

The regulation of the interaction between H2O2 and its catalysts is a promising route to achieve high productivity and selectivity towards H2O2. Herein, mesoporous anatase/TiO2(B) whisker (mb-TiO2) modified with heterogeneous carbon was prepared as the support of Pd-based catalysts for the direct synthesis of H2O2. The morphology and structure of the catalyst were investigated by transmission e...

Mesoporous Plasmonic Au-TiO2 Nanocomposites for Efficient Visible-Light-Driven Photocatalytic Water Reduction

The mesoporous Au-TiO2 nanocomposites with different Au concentrations were prepared via a co-polymer assisted sol-gel method. The structures have been characterized by powder X-Ray diffraction, N2 adsorption-desorption isotherms, diffuse reflectance UV-Vis spectroscopy, X-ray photoemission spectroscopy, transmission electron microscopy. Most generated Au nanoparticles were embedded in the meso...

Design and Synthesis of TiO2 Hollow Spheres with Spatially Separated Dual Cocatalysts for Efficient Photocatalytic Hydrogen Production

TiO₂ hollow spheres modified with spatially separated Ag species and RuO₂ cocatalysts have been prepared via an alkoxide hydrolysis-precipitation method and a facile impregnation method. High-resolution transmission electron microscopy studies indicate that Ag species and RuO₂ co-located on the inner and outer surface of TiO₂ hollow spheres, respectively. The resultant catalysts show significan...
