Enhanced Visible Light Controlled Glucose Photo-Reforming Using a Composite WO/Ag/TiO Photoanode: Effect of Incorporated Plasmonic Ag Nanoparticles.

WO/Ag/TiO composite photoelectrodes were formed via the high-temperature calcination of a WO film, followed by the sputtering of a very thin silver film and deposition of an overlayer of commercial TiO nanoparticles. These synthetic photoanodes were characterized in view of the oxidation of a model organic compound glucose combined with the generation of hydrogen at a platinum cathode. During prolonged photoelectrolysis under simulated solar light, these photoanodes demonstrated high and stable photocurrents of ca.

Photoelectrochemical Behavior of WO in an Aqueous Methanesulfonic Acid Electrolyte.

N-type semiconducting WO is widely investigated as a photoanode operating in water and seawater splitting devices. Because of the propensity of WO to favor photo-oxidation of acidic electrolyte anions and, in parallel, the formation on the electrode surface of the peroxo species, the choice of the appropriate electrolyte to allow stable operation of the photoanode is of critical importance. Our results from structural and photoelectrochemical tests performed using mesoporous WO photoanodes exposed to 80 h long photoelectrolysis in a 1 M aq.

Photoelectrocatalytic hydrogen generation coupled with reforming of glucose into valuable chemicals using a nanostructured WO photoanode.

Coupling the photo-oxidation of biomass derived substrates with water splitting in a photoelectrochemical (PEC) cell is a broadly discussed approach intended to enhance efficiency of hydrogen generation at the cathode. Here, we report a PEC device employing a nanostructured semitransparent WO photoanode that, irradiated with simulated solar light achieves large photocurrents of 6.5 mA cm through oxidation of glucose, a common carbohydrate available in nature that can be obtained by processing waste biomass.
