Reduction of nitrates by dihydrogen in CeO2 and Rh/CeO2 catalysts
Applied Catalysis A: General, 1992Abstract Series of NO 3 − /CeO 2 and Rh/NO 3 − /CeO 2 catalyst with variable loadings of nitrate (0-1.5 wt.-%) and of rhodium (0-0.2 wt.-%) were prepared by impregnation of a cerium oxide (19 m 2 g −1 ) with aqueous solutions of sodium nitrate and of rhodium nitrate. The catalysts were dried at 120 ° C and characterized by temperature-programmed

Effects of CeO2 nanoparticles on electrochemical properties of carbon/CeO2 composites
Applied Surface Science, 2018Abstract The electrochemical properties of carbon were improved when composited with CeO2 nanoparticles making this material a candidate for high performance energy storage devices. Carbon was obtained from coffee husks by calcining at a temperature of 600 °C for 1 h.

Study of CeO2 XPS spectra by factor analysis: reduction of CeO2
Applied Surface Science, 2000Abstract The evaluation of the reduction state of CeO2 by XPS is still controversial because of the presence of more than 10 peaks in the Ce(3d) photoemission spectra due to Ce3+ and Ce4+, some of them at similar binding energies. This makes difficult conventional fitting using nonlinear least-square (NLLSF) methods with Gaussian–Lorentzian curves ...

Electrochemical synthesis of CeO2 and CeO2/montmorillonite nanocomposites.
Nanocrystalline cerium oxide thin films on metal and semiconductor substrates have been fabricated with a novel electrodeposition approach - anodic oxidation. X-ray diffraction analysis indicated that as-produced cerium oxide films are characteristic face-centered cubic fluorite structure with 5 ~ 20 nm crystal sizes.openaire +1 more source

SAXS and WAXS on TiO2, CeO2 and CeO2 and CeO2-SnO2 Thin Films at Grazing Angles
1999In SAXS - beamline on ELETTRA we have measured SAXS and WAXS of thin films CeO2, CeO2-SnO2 and TiO2 on glass substrate in reflection geometry at grazing angles from 0.18 to 1 degrees.

The CO2–CeO2 interaction and its role in the CeO2 reactivity
Catalysis Letters, 1998The interaction between CO2 and CeO2 and its role in the surface reactivity of alumina-supported cerium oxide has been studied by programmed thermodesorption (TPD) of CO2 and FTIR spectroscopy. The performance of Ce/Al2O3 systems was then analyzed for the propane oxidation in presence of CO2. The results have shown that the catalytic activity decreased
