Resumo: In this work, thin films of Eu3+, Tb3+ and Tm3+ doped CeO2 in the proportions of 2 and 4 mol% were obtained by spin coating and calcined at 700 °C. The films were characterized by XRD, SEM, AFM and UV-Vis techniques. The photocatalytic activity of the thin films was measured by the degradation of the methylene blue (MB) dye. The thin films were submitted to 4 photocatalytic cycles to analyze the capacity to be reused. The diffractograms show that was no secondary phase formation, where all characteristic peaks are related to CeO2. SEM micrographs indicate that doping at 4 mol% promotes the reduction in the thickness and surface porosity of the thin films. AFM images indicate the increase in surface roughness with rare earths doping. Doping with Eu3+, Tb3+ and Tm3+ increased the degradation of the methylene blue dye by at least 15% for thin films doped at 4 mol%. The reuse tests indicate that the photocatalytic activity remains practically constant even with the application of four consecutive cycles.

Os filmes foram caracterizados pelas técnicas de DRX, FEG, MFA e UV-Vis. As propriedades fotocatalíticas dos filmes finos foram determinadas pela degradação do corante azul de metileno (AM). Os filmes finos foram submetidos a 4 ciclos fotocatalíticos para analisar a capacidade de serem reusados. Os difratogramas mostram que não houve a formação de fases secundárias, onde todos os picos são referentes ao CeO2. As micrografias de FEG indicam que a dopagem com 4 %mol promove a redução da espessura e porosidade superficial dos filmes finos. As imagens de MFA indicam o aumento da rugosidade superficial com a dopagem utilizando terras raras. A dopagem com Eu3+, Tb3+ e Tm3+ aumentam a atividade fotocatalítica em pelo menos 15%, para os filmes dopados com 4 %mol. Os testes de reuso indicam que a atividade fotocatalítica se mantém praticamente constante após a aplicação de quatro ciclos consecutivos.Universidade Federal do Rio Grande do NorteUFRNBrasilEngenharia de MateriaisAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessEu3+, Tb3+ and Tm3+ doped CeO2; thin films; spin coating; photocatalytic reuseCeO2 dopado com Eu3+, Tb3+ e Tm3+; filmes finos; spin coating; reuso fotocatalíticoStudy of obtaining thin films of CeO2 doped with 2 and 4 mol% of europium, terbium and thulium obtained by spin-coating: Photocatalytic propertiesEstudo da obtenção de filmes finos de CeO2 dopados com 2 e 4 %mol de európio, térbio e túlio obtidos por spin-coating: Propriedades fotocatalíticasinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisengreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTMODELO ARTIGO CEMat1.pdf.txtExtracted texttext/plain3769https://repositorio.ufrn.br/bitstream/123456789/40355/1/MODELO%20ARTIGO%20CEMat1.pdf.txt7083722fc520e14fc06bc08aa0db07d3MD51ORIGINALMODELO ARTIGO CEMat1.pdfapplication/pdf599590https://repositorio.ufrn.br/bitstream/123456789/40355/2/MODELO%20ARTIGO%20CEMat1.pdf7711179c607468555516aaa75a001c71MD52CC-LICENSElicense_rdfapplication/octet-stream811https://repositorio.ufrn.br/bitstream/123456789/40355/3/license_rdfe39d27027a6cc9cb039ad269a5db8e34MD53LICENSElicense.txttext/plain762https://repositorio.ufrn.br/bitstream/123456789/40355/4/license.txte428689918449bd69f843393981e4109MD54123456789/403552021-09-29 10:22:34.021oai:https://repositorio.ufrn.br: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ório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2021-09-29T13:22:34Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false
