Abstract
SnO2 micro/nano fibers in the rutile structure were synthesized using electrospinning and metallorganic decomposition techniques. Fibers were electrospun using two different precursor solutions, one based on SnCl4 and the other on C22H44O4Sn. The fibers were sintered in air for two hours at 400, 500, 600, 700 and 800°C. SEM, AFM, XRD, XPS and Raman microspectrometry were used to characterize the sintered fibers. The results showed that the fibers were composed of SnO2 and that the SnCl4 precursor led to better results in terms of uniformity/continuity of the fibers.
Keywords: Tin oxide; nanofibers; electrospinning.
Resumen
Micro/nano fibras SnO2 de rutilo se sintetizaron con electrospinning y técnicas de descomposición metaloorgánicas. Las fibras se produjeron utilizando dos soluciones precursoras distintas basadas en una mezcla de SnCl4 y otra de C22H44O4Sn. Las fibras se quemaron en aire por dos horas a temperaturas de 400, 500, 600, 700 y 800° C y se analizaron utilizando SEM, AFM, XRD, XPS y microscopía Raman. Los resultados muestran que las fibras producidas con ambos precursores están compuestas de SnO2 y que la solución precursora con SnCl4 produce fibras más uniformes y continuas.
Descriptores: Óxido de estaño; nanofibras; electrospinning.
