This paper describes the synthesis, morphological and structural characterization of nanoporous aluminum oxide templates (Al2O3) and tin oxide nanowires (SnOx). The templates of Al2O3 with tin deposition were treated thermally at 400, 450, 500 and 550 °C to obtain tin oxide (SnOx). The different sam...

| description | This paper describes the synthesis, morphological and structural characterization of nanoporous aluminum oxide templates (Al2O3) and tin oxide nanowires (SnOx). The templates of Al2O3 with tin deposition were treated thermally at 400, 450, 500 and 550 °C to obtain tin oxide (SnOx). The different samples were characterized by Scanning Electron Microscopy (SEM), Dispersive Energy Spectroscopy (EDS) and X-ray Diffraction (XRD). SEM images present a homogeneous pore distribution over the templates of Al2O3 with an estimated porosity value of 19.7%. The morphological parameters obtained from these images show pores size with an average diameter of 24.4 nm, and a nanoporous template thickness of 12.0 µm. Pore density was estimated in samples of approximately 4.27 x107 pores/cm2. The XRD patterns of the prepared samples evidence the formation of the nanocrystalline structure phase rutile, SnO2, for the sintered samples at 550 °C. The properties of nanostructured materials from SnO2 are responsible for many technological applications that are interesting in the field of material science. The results presented demonstrate that the methodologies used in the synthesis of nanowires from SnO2 produce a good quality nanostructure for potential applications such as gas sensors. |

Las plantillas de Al2O3 con deposición de estaño fueron tratadas térmicamente a 400, 450, 500 y 550 °C para la obtención de óxido de estaño (SnOx). Las diferentes muestras fueron caracterizadas por microscopía electrónica de barrido (SEM), espectroscopía de energía dispersiva (EDS) y difracción de rayos X (XRD). Las imágenes SEM presentan una distribución homogénea de poros sobre las membranas de Al2O3 con un valor estimado de porosidad de 19.7%. Los parámetros morfológicos obtenidos a partir de estas imágenes muestran tamaño de poros con diámetro promedio de 24.4 nm, y espesor de plantilla nanoporosa de 12.0 µm. Se estimó la densidad de poros en las muestras de aproximadamente 4.27x107 poros/cm2. Los patrones de XRD de las muestras preparadas evidencian la formación de la estructura nanocristalina fase rutilo, SnO2, para las muestras sinterizadas a 550 °C. Las propiedades de materiales nanoestructurados de SnO2 son responsables de un gran número de aplicaciones tecnológicas que resultan interesantes en el campo de la ciencia de los materiales. Los resultados presentados demuestran que las metodologías empleadas en la síntesis de nanohilos de SnO2 producen buena calidad de nanoestructuras para potenciales aplicaciones como sensores de gases.Universidad Tecnológica de Panamá2020-01-282021-05-12T23:22:01Z2021-06-01T05:41:58Z2021-05-12T23:22:01Z2021-06-01T05:41:58Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/243510.33412/idt.v16.1.2435https://ridda2.utp.ac.pa/handle/123456789/130982219-67141680-8894I+D Tecnológico; Vol. 16 Núm. 1 (2020): Revista de I+D Tecnológico; 22-29reponame:Repositorio Institucional de documento digitales de acceso abierto de la UTPinstname:Universidad Tecnológica de Panamáinstacron:U Tecnológica de Panamáspahttps://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/2435/3262https://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/2435/3519info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/4.0/oai:ridda2.utp.ac.pa:123456789/130982021-06-01T05:41:58Z |
