Abstract:Cerium iron mixed oxide (CFO) nanocomposite materials supported on spherical silica particles were explored for gas phase dehydration of isopropyl alcohol (IPA). The samples were formed by a sol-gel process. Utilization of silica as a matrix for reducible CeO2-Fe2O3 mixed oxides formation of thermally stabilized textural CeO2-Fe2O3 /silica nanocomposite materials, Thus, a series of 10-30% (w/w) CFO/silica was directly formed, dried, and calcined at 550 o C. XRD, TG-DTA, ATR-FTIR, nitrogen adsorption−desorption… Show more
