Photocatalytic methane activation by dual reaction sites co-modified WO3

Photocatalytic degradation of an organophosphorus compound by porous Au- and WO3- modified TiO2

Enhanced photoelectrochemical and photocatalytic activity of WO3-surface modified TiO2 thin film

Development of nanostructured photocatalysts for harnessing solar energy in energy-efficient and environmentally benign way remains an important area of research. Pure and WO3-surface modified thin films of TiO2 were prepared by magnetron sputtering on indium tin oxide glass, and photoelectrochemical and photocatalytic activities of these films were studied. TiO2 particles were <50 nm, while de...

Dual reaction channels for photocatalytic oxidation of phenylmethanol on anatase.

This work explores thoroughly the reaction network of the partial oxidation of phenylmethanol at the TiO(2)-solvent interface under photocatalytic conditions by using a first-principles continuum solvation method. We demonstrate that the photocatalytic oxidation of phenylmethanol has a complex reaction network with dual pathways. The dimer pathway dominates the mechanism under aerobic condition...

Synthesis and Characterization of WO3/Graphene Nanocomposites for Enhanced Photocatalytic Activities by One-Step In-Situ Hydrothermal Reaction

Tungsten trioxide (WO₃) nanorods are synthesized on the surface of graphene (GR) sheets by using a one-step in-situ hydrothermal method employing sodium tungstate (Na₂WO₄·2H₂O) and graphene oxide (GO) as precursors. The resulting WO₃/GR nanocomposites are characterized by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, scanning electron microscopy and X-ray photoelectro...

Synthesis of Shape-Tailored WO3 Micro-/Nanocrystals and the Photocatalytic Activity of WO3/TiO2 Composites

A traditional semiconductor (WO₃) was synthesized from different precursors via hydrothermal crystallization targeting the achievement of three different crystal shapes (nanoplates, nanorods and nanostars). The obtained WO₃ microcrystals were analyzed by the means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and diffuse reflectance spectroscopy (DRS). These methods contributed...
