Title
Low-temperature efficient degradation of ethyl acetate catalyzed by lattice-doped CeO2–CoOx nanocomposites
Abstract

•Exceptionally low temperature for ethyl acetate degradation by CeO2–CoOx nanocomposite•Higher catalytic activity of nanocomposite than its individual components.•Enhanced catalytic activity caused by the increase of lattice oxygen due to lattice doping.

A series of CeO2–CoOx nanocatalysts have been synthesized by a facile surfactant-free hydrothermal method and investigated for the oxidative degradation of ethyl acetate (EA) at exceptionally low temperature. The combination of various techniques, such as H2-TPR, XRD, XPS and HRTEM provides insights to the effect of various factors including redox properties, enhanced lattice oxygen and its mobility etc. on catalysis performance. The results demonstrate that the enriched lattice oxygen is the dominant factor for the low-temperature degradation of EA due to the interaction between lattice-mixed Ce and Co ions, which can be used to design the catalysts for removing VOCs with improved performance.
