Oxidación de glicerol por titania fluorada y platinizada

Resumen
En el presente trabajo se evaluó TiO2 fluorizado y platinizado en la oxidación del glicerol. La fluorización permitió incrementar el área superficial de la titania y la platinización llevó a obtener una mayor absorción en la región visible del espectro electromagnético; así, 0.5 wt.% Pt-F-TiO2 fue el mejor catalizador en la obtención del mayor rendimiento y selectividad hacia gliceraldehído (GAL). También se encontró que un contenido de 2% de Pt tiene un efecto negativo sobre la conversión de glicerol. La fluorización y la adición de platino llevaron a modificar el mecanismo de reacción y la selectividad.
