A catalytic application of Cu2O and CuO films deposited over fiberglass

With the purpose of utilizing copper oxides over fiberglass as a novel cata lyst material in oxidation reactions, we have used the chemical vapor depos ition of 2,4-pentanedionate copper(II) as a precursor and fiberglass as sub strate. The deposition of copper oxides was achieved in a horizontal-flow r eactor using O-2 as carrier-reactant gas at several deposition temperatures . Copper species deposited on fiberglass were characterized by X-ray diffra ction (XRD), UV-visible spectrophotometry (UV-VIs) and scanning electronic microscopy (SEM) techniques. The fiberglass coated with copper oxides showe d a catalytic activity for the oxidation of ethanol into a stream of air at different temperatures in a pulse microreactor.
