Facile synthesis of efficient visible active C-doped TiO2 nanomaterials with high surface area for the simultaneous removal of phenol and Cr(VI)

A single step synthesis of carbon doped TiO2 (anatase) nanomaterials have been reported by using combustion synthesis using ascorbic acid and citric acid fuels. X-ray diffraction studies indicated the formation of nanosized anatase titania, whereas, transm ...

TaOxNy Sputtered Photoanodes For Solar Water Splitting

Michael Graetzel, Rosendo Sanjines, Nicolas Xanthopoulos, Maurin Cornuz, Vincent Laporte, Kevin Sivula

A series of TaOxNy photoelectrodes were deposited on F:SnO2 (FTO) substrates by DC reactive sputtering at room temperature, under a mixture of Ar, N-2 and O-2. The effects of the O-2 partial pressure during deposition (Po-2) on the films crystallinity, the ...

LaTiO2N/In2O3 photoanodes with improved performance for solar water splitting

Michael Graetzel, Rosendo Sanjines, Nicolas Xanthopoulos, Kevin Sivula, Takashi Hisatomi

LaTiO2N photoanodes for solar water splitting were prepared by electrophoretic deposition and demonstrated the best photo-currents ever reported for this material. Further important enhancement of the performance was obtained by the use of a sputtered In2O ...
