Abstract

Abstract: Novel ZrSn1− x Co x O4− δ catalysts for the direct decomposition of nitrous oxide (N2 O) were synthesized using a co‐precipitation method. Metastable ZrSnO4 with an α‐PbO2 ‐type structure was used as the mother solid because of its interstitial open spaces derived from its lattice distortion that may be effective for N2 O adsorption. The doping of Co 2+/3+ into the ZrSnO4 lattice improved the N2 O decomposition activity, likely owing to the enhancement of the redox properties and the increase in the number of oxygen vacancies. Among the prepared catalysts, Zr1.17 Sn0.73 Co0.10 O4− δ exhibited the highest activity decomposing N2 O completely decomposed at 550°C. In addition, the Zr1.17 Sn0.73 Co0.10 O4− δ catalyst showed high durability in the presence of CO2, O2, and H2 O vapor.
