“…This signal is correlated with the level of defects in the samples26, thereby suggesting that both facts are intimately related26. Therefore, in the most pure and partially reduced CeO 2 samples, this signal has a very low intensity28 or is even absent29. Besides, its intensity does not correlate with the degree of reduction of the samples26.…”

ABSTRACT:The high performance of cerium dioxide (CeO 2 ) as support for Au in catalysis relies on its ability to anchor Au clusters and transfer charge to the gold nanoparticles. These two processes are governed by oxygen vacancy formation. To study the localization and the mobility of the electrons left behind by the vacancy from the relaxed oxygen, an experimental and theoretical study is hereby reported. CeO 2 powder was synthesized by the polyacrylamide gel method and its microstructure was characterized by X-ray diffraction and high resolution scanning electron microscopy. We have determined the presence of only the fluorite cubic phase in our samples and the formation of acicular particles of $1 lm in length. In the electron spin resonance study, we observed that the unpaired electrons are quasi free. A single-line paramagnetic signal is observed that exhibits spin characteristics with a g-value of 2.0039 at room temperature. This compares well to the value of 2.0023 determined for free electrons. In addition, we have conducted a theoretical study using a density functional theory cluster approach and calculate the electron spin density of CeO 2 clusters. We find that spin density clouds are localized around the cerium ions.

“…However this needs to be confirmed. The effect of DSG on the inhibition of GCA was first reported by Nagamine et al 11 Zhang et al 17 further showed that DSG may inhibit PDGF-A chain mRNA expression in rat cardiac allografts. The protective effects against GCA of DSG over those of CsA may result from its different immunosuppressive actions.…”

“…CeO 2 has been intensely studied for solid oxide fuel cells and catalytic applications due to its rich oxygen vacancies and low redox potential via the Ce 4+ /Ce 3+ redox cycle. [117][118][119] CeO 2 can also be a promoter for improving the ORR activity and durability of Pt/C catalysts. Lee et al developed an effective method for preparing highly dispersed CeO 2 NPs on Pt/C catalyst.…”

Low temperature fuel cells (LTFCs) have received broad attention due to their low operating temperature, virtually zero emissions, high power density and efficiency. However, the limited stability of the catalysts is a critical limitation to the large scale commercialization of LTFCs. State of the art carbon supports undergo corrosion under harsh chemical and electrochemical oxidation conditions, which results in performance degradation of catalysts. Therefore, non-carbon materials which are highly oxidation resistant under strongly oxidizing conditions of LTFCs are ideal alternative supports. This minireview highlights the advances and scenarios in using nano-ceramics as supports to enhance the stability of catalysts, the solutions to improve electrical conductivity of nano-ceramic materials, and the synergistic effects between metal catalyst and support to help improve the catalytic activity and CO/SO2 tolerance of catalysts.
