Deactivation of a Au/CeO2–Co3O4 catalyst during CO preferential oxidation i…
Abstract. The origins of the deactivation of a Au/CeO2–Co3O4 catalyst during CO preferential oxidation (PROX) are investigated in detail by means of high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction of hydrogen (H2-TPR), temperature-programmed oxidation of oxygen (O2-TPO), and diffuse …

CO2 Reforming of CH4 on Ni(111): A Density Functional Theory Calculation
CO2 reforming of CH4 on Ni(111) was investigated by using density functional theory. On the basis of thermodynamic analyses, the first step is CH4 sequential dissociation into surface CH (CH4 f CH3 f CH2 f CH) and hydrogen, and CO2 dissociation into surface CO and O (CO2 f CO + O). The second step is CH oxygenation into CHO (CH + O f CHO), which is more favored than dissociation into C and h…
