Title
Study of thin films of yttria-stabilized zirconia (YSZ) for the oxidation of some volatile organic compounds
Abstract

•YSZ and 1%Pt/YSZ thin films deposited on stainless steel by an electrophoretic route•Use of the inductive heating in TPD, intermittent TPD and catalytic tests•Study of oxygen species desorbed by YSZ and 1%Pt/YSZ thin films•Evaluation of YSZ and 1%Pt/YSZ thin films in isopropanol and toluene abatement

Thin films of YSZ and 1%Pt/YSZ were deposited onto stainless steel tubes by an electrophoretic deposition technique. O2-TPD from r.t. to 600 °C using induction heating was used to characterize the two films considering (i) the amount of oxygen desorbed (5.1 and 1.4 × 10− 2 μmol O2·g− 1 for 1%Pt/YSZ and YSZ respectively) and (ii) the apparent activation energy of desorption Eapp. Finally, complete oxidation of some VOCs (isopropanol and toluene) in air was studied on both films. From r.t. to 400 °C, oxidation of isopropanol can be achieved with either YSZ or 1%Pt/YSZ but only this last catalyst can achieve the complete oxidation of toluene.
