Crystal growth and design of various shapes of PbS micro and nanocrystals from a hydrothermal process

Jemai, Safa; Hajjaji, Anouar; Baig, Faisal; Harabi, Imen; Marí, B.; Bessais, Brahim (Elsevier, 2021-05)

[EN] This paper reports on a systematic study highlighting dramatic morphological changes during the preparation of Lead Sulfide (PbS) by a hydrothermal process. PbS micro/nanostructures having different shapes and sizes ...
Cu-Doped TiO<sub>2</sub> Thin Films by Spin Coating: Investigation of Structural and Optical Properties

Sassi, Syrine; Bouich, Amal; Hajjaji, Anouar; Khezami, Lotfi; Bessais, Brahim; Marí, B. (MDPI, 2024-07)

[EN] Cu-doped TiO2 films were synthesized directly on FTO glass with a spin coating method. With a variation in copper amount, samples were prepared with 0%, 1%, 2%, 4% and 8% of dopant concentrations. Morphological and ...
Electrochemical Fabrication and Characterization of p-CuSCN/n-Fe2O3 Heterojunction Devices for Hydrogen Production

Bouhjar, Feriel; Ullah, Shafi; Mollar García, Miguel Alfonso; Marí, B.; Bessais, Brahim (The Electrochemical Society, 2017)

[EN] p-CuSCN/n-Fe2O3 heterojunctions were electrochemically prepared by sequentially depositing alpha-Fe2O3 and CuSCN films on FTO (SnO2:F) substrates. Both alpha-Fe2O3 and CuSCN films and alpha-Fe2O3/CuSCN heterojunctions ...
Electrodeposited chromium-doped alpha-Fe2O3 under various applied potential configurations for solar water splitting

Bouhjar, Feriel; Derbali, Lotfi; Marí, B.; Bessais, Brahim (Elsevier, 2020-06)

[EN] In this work, high quality hematite (alpha-Fe2O3) Chromium (Cr)-doped thin films have been synthesized via electrodeposition technique, on fluorine-doped fin oxide-coated glass substrates, under various applied potential ...
Electrodeposited Cr-Doped alpha-Fe2O3 thin films active for photoelectrochemical water splitting

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