The β-Bi2O3 sol precursor properties were characterized by DLS, SEM, and X-ray diffraction. The composition and morphology of the films were characterized by SEM-EDS. The photoelectrochemical characterization was performed by linear sweep voltammetry with chopped light irradiation and photocurrent measurements. The photoelectrocatalytic activity of the films under UV-Vis and visible light irradiation was conducted on the oxidation of salicylic acid. Results show that the films are composed of a TiO2 layer with Bi2O3 particles dispersed throughout the surface. X-ray diffraction results confirm that the Bi2O3 obtained from the sol precursor prepared corresponds to β-tetragonal phase. The linear sweep voltammetry shows that the β-Bi2O3-TiO2/ITO films have a higher photocurrent in the anodic region than TiO2/ITO films used as reference. The photoelectrocatalytic activity of the β-Bi2O3-TiO2/ITO films on the oxidation of salicylic acid under visible light irradiation was higher than TiO2/ITO films. The results show that the β-Bi2O3-TiO2/ITO films are active under visible light and can be used in photoelectrochemical cells.application/pdfhttps://doi.org/10.1007/s10008-019-04270-01432-84881433-0768https://repositorio.udes.edu.co/handle/001/3069engSpringer-Verlag GmbH Germany, Journal of Solid State Electrochemistry, 2019Journal of Solid State ElectrochemistryDerechos Reservados - Journal of Solid State Electrochemistry, 2019info:eu-repo/semantics/openAccessAtribución-NoComercial 4.0 Internacional (CC BY-NC 4.0)https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf2https://link.springer.com/article/10.1007%2Fs10008-019-04270-0Precipitation-peptization methodHeterojunctionNanoparticlesSalicylic acid oxidationPhotoelectrochemical activityEnhanced visible light photoelectrochemical performance of β-Bi2O3-TiO2/ITO thin films prepared by aqueous sol-gelArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85PublicationTEXTEnvironmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdf.txtEnvironmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdf.txtExtracted texttext/plain2https://repositorio.udes.edu.co/bitstreams/dfa02ca6-ee95-4a80-90fd-93b7bc663383/downloadd784fa8b6d98d27699781bd9a7cf19f0MD56LICENSElicense.txtlicense.txttext/plain; charset=utf-859https://repositorio.udes.edu.co/bitstreams/16271de3-fe35-4043-b171-d846389203d4/download38d94cf55aa1bf2dac1a736ac45c881cMD52ORIGINALEnvironmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdfEnvironmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdfapplication/pdf121729https://repositorio.udes.edu.co/bitstreams/59b10f24-0f19-4a2a-9374-575c7599fe00/download197201f487e7a0230429b500c6b52a09MD55BRANDED_PREVIEWEnhanced visible light photoelectrochemical performance of β-Bi2O3-TiO2-ITO thin films prepared by aqueous sol-gel.PNG.preview.jpgEnhanced visible light photoelectrochemical performance of β-Bi2O3-TiO2-ITO thin films prepared by aqueous sol-gel.PNG.preview.jpgGenerated Branded Previewimage/jpeg6183https://repositorio.udes.edu.co/bitstreams/ca60dd2e-768a-46cd-a4d2-aa1bab70a907/download07453641c522c2b39c0a87bfc98c680eMD54THUMBNAILEnhanced visible light photoelectrochemical performance of β-Bi2O3-TiO2-ITO thin films prepared by aqueous sol-gel.PNG.jpgEnhanced visible light photoelectrochemical performance of β-Bi2O3-TiO2-ITO thin films prepared by aqueous sol-gel.PNG.jpgUDESimage/jpeg1650https://repositorio.udes.edu.co/bitstreams/59596fa1-9fbc-4512-a125-17448bc6f384/downloadedbe07302dd2e4620fa2edebe0cc6055MD53Environmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdf.jpgEnvironmental and socioeconomic determinants of leptospirosis incidence in Colombia.pdf.jpgGenerated Thumbnailimage/jpeg1596https://repositorio.udes.edu.co/bitstreams/572c03f7-c3ee-42e4-ac8b-a2dd5a5256fb/downloade02473f00e3869cf8872569a7ef3e95cMD57001/3069oai:repositorio.udes.edu.co:001/30692023-10-11 10:22:19.129https://creativecommons.org/licenses/by-nc/4.0/Derechos Reservados - Journal of Solid State Electrochemistry, 2019https://repositorio.udes.edu.coRepositorio Universidad de Santandersoporte@metabiblioteca.comTGljZW5jaWEgZGUgUHVibGljYWNpw7NuIFVERVMKRGlyZWN0cmljZXMgZGUgVVNPIHkgQUNDRVNPCgo=
