摘要: A series of CeO2-CoOx nanocatalysts have been synthesized by a facile surfactant-free hydrothermal method and investigated for the oxidative degradation ethyl acetate (EA) at exceptionally low temperature. The combination various techniques, such as H-2-TPR, XRD, XPS HRTEM provides insights to effect factors including redox properties, enhanced lattice oxygen its mobility etc. on catalysis performance. results demonstrate that enriched is dominant factor low-temperature EA due interaction between lattice-mixed Ce Co ions, which can be used design catalysts removing VOCs with improved (C) 2015 Elsevier B.V.
