The effect of calcination temperature on the oxygen storage and release properties of CeO2 and Ce–Zr–O metal oxides modified by phosphorus incorporation

Electrochemical Analysis of a System Based on W and Ni Combined with CeO2 as Potential Sulfur‐tolerant SOFC Anode

“…In addition, significant peaks located at binding energy 882. ) eV, respectively, that are consistent with the presence of the Ce 3+ [13,14]. The aforementioned XPS results were in good agreement with the XRD results, and implied that the cerium is as Ce 4+ in both fresh and reduced samples and as Ce 3+ in the sample exposed to H 2 S. The sulfur S 2p spectrum ( Figure 2b) reveals one peak at BE of 161.2 eV and the other at 168.9 eV.…”

“…According to the thoroughly accepted convention suggested by Burroughs et al [12], Ce 3d 5/2 multiplets are labelled v, whereas those of 3d 3/2 are labelled u. In the fresh sample, the Ce spectrum contained three main 3d 5 [13,14].…”

In situ structural changes during toluene complete oxidation on supported EuCoO3 monitored with 151Eu Mössbauer spectroscopy

“…Ceria-based materials and zirconia were reported as good carriers, leading to no interaction with the most common cations of perovskites [15][16][17]. In many occasions, they were found to provide an adequate surface area such as the case of cerium-based materials having good oxygen storage-and-release properties [18,19]. At the same time, some studies on Co-based perovskites showed that in a reductive atmosphere Co can be reduced to Co 0 .…”

Preparation of ceria-zirconia solid solution with enhanced oxygen storage capacity and redox performance

“…The decrease of reduction temperature suggested that if the materials be employed in TWCs, there would be an enhancement of oxygen ions mobility and easy redox cycle that would facilitate catalytic activity at low temperatures and lessen automobile emissions under fuel-rich conditions. The amount of labile oxygen (most reactive oxygen) of the catalyst is called "oxygen storage capacity" (OSC) [25]. The release of oxygen from the Ce 1 -x Zr x O 2 solid solution at low temperatures was well known as a simple and useful tool to detect the deactivation of OSC and enhancement of TWC activity [21,26].…”
