Abstract
Ceria-supported transition metal oxide (such as CoOx) catalysts are promising, more cost-effective candidates to replace platinum group metal catalysts in the NO reduction process. A series of CoOx (0.2–31.3 Co/nm2) catalysts supported on CeO2 were prepared by the incipient wetness impregnation method and were tested for NO reduction by CO reaction in this work. Various characterization techniques, including Brunauer–Emmett–Teller, Raman spectroscopy, powder X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) were used to investigate the molecular and electronic structures of CoOx/CeO2 catalysts. It was observed that there are structural changes with varied Co loadings, such as (1) sub-monolayer: 2.7 Co/nm2. The highest molar rate was observed at the 2.7 Co/nm2 sample. In the case of over-monolayer samples, such as 7.1 Co/nm2, the oxidation state of Co aff...
