Direct decomposition of N2O over Co3O4/ZrSn1−xFexO4−δ catalysts

Abstract

This study focuses on the development and characterization of precious-metal-free Co3O4/ZrSn[Formula: see text]Fe[Formula: see text]O[Formula: see text] catalysts for the purpose of direct N2O decomposition. The oxygen supply from ZrSn[Formula: see text]Fe[Formula: see text]O[Formula: see text] facilitated N2O decomposition. Among the prepared catalysts, the 19 wt.% Co3O4/ZrSn[Formula: see text]Fe[Formula: see text]O[Formula: see text] catalyst exhibited the highest catalytic activity. Furthermore, N2O was completely decomposed at a relatively low temperature of 500[Formula: see text]C.
