Abstract | Two kinds of nano-CeO2-supported low loading Ru catalysts were prepared by ultrasonic-assisted incipient wetness impregnation method and their applications in catalytic wet air oxidation (CWAO) of butyric acid (BA) were investigated. Both of the catalysts were characterized by XRD, XPS, TEM, N2 adsorption–desorption, Raman and H2-TPR. According to the characterization results, compared to Ru/CeO2 catalyst, the active component was well dispersed on the support and the particle sizes were smaller for the Ru/CeO2-A catalyst which was added to some absolute ethanol in the process of preparation. Meanwhile, Ru/CeO2-A catalysts possessed a high active surface area and had a higher Ce3+ and oxygen vacancy content due to the strong interaction between Ru species and CeO2. Therefore, the Ru/CeO2-A catalyst presented higher catalytic activity and the chemical oxygen demand (COD) removal can increase up to 64.05% after 2 h. It had excellent stability and can be reused many times without obvious loss of activity. |
