New catalytic system for oxidation of isopropyl alcohol with thin film catalysts

• Novel system for studying thin film catalysts used for VOC treatment
• Inductive heating allowed very fast catalyst heating with good temperature control.
• Thin adherent catalyst films on steel were obtained by electrophoretic deposition.
• Full abatement of IPA is obtained even at high heating rate (400 °C·min− 1).

This paper describes a new catalytic system developed to study catalysts deposited as thin films on a metallic support. This device uses the electromagnetic induction for heating the metallic support. Therefore, it enables homogeneous sample heating, up to 400 °C·min− 1 with a good regulation and a very low thermal inertia allowing fast cooling and accurate hold on temperature plateau. Catalysts SnO2, 0.3 and 1 wt.% Pt on SnO2 were deposited on stainless steel by an electrophoretic technique and evaluated in the abatement of isopropyl alcohol in air, a common model for VOCs.
