Photodegradation of Methylene Blue using Nb-doped titania nanotubes with adsorption and photocatalytic properties Thiam, Abdoulaye Sirés Sadornil, Ignacio Cabot Julià, Pere-Lluís Alcaide, Francisco Adsorció Nanotubs Fotocatàlisi Adsorption Nanotubes Photocatalysis The development of materials for the effective photoremoval of contaminants using eco-friendly methods is challenging. This study reports the synthesis of Nb-doped titania nanotubes (TNTs) and Nb-doped TiO2 nanoparticles for application in photocatalysis. Their performance was assessed from color removal of Methylene Blue solutions. Morphological characterization showed that Nb-doped TNTs had a porous network structure made up of nanotubes and nanosheets with a large aspect ratio. The lowest pore diameter alongside uniform pore size distribution were obtained with Nb-doped TNTs at 6 at.% Nb, which yielded the highest performance. Nb-doped TNTs may become a prominent photocatalyst for water treatment. 2023-04-28T17:16:06Z 2025-02-08T06:10:09Z 2023-02-08 2023-04-28T17:16:06Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0167-577X https://hdl.handle.net/2445/197409 730256 eng Versió postprint del document publicat a: https://doi.org/10.1016/j.matlet.2023.134024 Materials Letters, 2023, vol. 338, p. 134024 https://doi.org/10.1016/j.matlet.2023.134024 cc-by-nc-nd (c) Elsevier B.V., 2023 https://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess application/pdf Elsevier B.V.
