Electrodeposited Cr-Doped alpha-Fe2O3 thin films active for photoelectrochemical water splitting

Bouhjar, Feriel; Derbali, Lotfi; Marí, B.; Bessais, Brahim (Elsevier, 2020-04-14)

[EN] Polycrystalline hematite (alpha-Fe2O3) Chromium (Cr)-doped thin films were electrodeposited on fluorine-doped tin oxide-coated glass substrates. The electrodeposition bath comprised an aqueous solution containing FeCl3 ...
Hematite as an Electrocatalytic Marker for the Study of Archaeological Ceramic Clay bodies: A VIMP and SECM Study**

Doménech-Carbó, Antonio; Giannuzzi, Michele; Mangone, Annarosa; Giannossa, Lorena Carla; Di Turo, Francesca; Cofini, Elena; Domenech Carbo, Mª Teresa (John Wiley & Sons, 2022-01-27)

[EN] The electrocatalytic effect exerted by hematite, a ubiquitous component of clay bodies, on the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) can be used to acquire information on archaeological ...
Hydrothermal synthesis of nanostructured Cr-doped hematite with enhanced photoelectrochemical activity

Bouhjar, Feriel; Mollar García, Miguel Alfonso; Chourou, M.L.; Marí, B.; Bessais, Brahim (Elsevier, 2018)

[EN] Using the easily applicable hydrothermal method Cr-doped hematite thin films have been deposited polycrystalline on conductive glass substrates. The hydrothermal bath consisted of an aqueous solution containing a ...
Preparation et performance d'une cellule photocatalytique à base d'hématite pour la génération d'hydrogène

Bouhjar, Feriel (Universitat Politècnica de València, 2018-07-27)

El hidrógeno es un portador de energía que ya ha demostrado su capacidad para reemplazar el petróleo como combustible. Sin embargo, los medios de producción actualmente en uso siguen siendo altamente emisores de gases de ...
Study of the annealing conditions and photoelectrochemical characterization of a new iron oxide bi-layered nanostructure for water splitting

Lucas-Granados, Bianca; Sánchez Tovar, Rita; Fernández Domene, Ramón Manuel; Garcia-Anton, Jose (Elsevier, 2016-08)

Iron oxide nanostructures have emerged as promising materials for being used as photocatalysts for hydrogen production due to their advantageous properties. However, their low carrier mobility and short hole diffusion ...
