TL;DR: In this paper, the reduction of CeO2 by hydrogen has been studied from 300-1200 K by several complementary techniques: temperature-programmed reduction (TPR), magnetic susceptibility measurements, Fourier transform infrared (FTIR), UV-VIS diffuse reflectance and X-ray photoelectron (XP) spectroscopy.
Journal ArticleDOI
Reduction of cerias with different textures by hydrogen and their reoxidation by oxygen
TL;DR: In this article, a direct relationship between the degree of reduction and the BET surface area was established using the area of low-temperature TPR composite peak, the maximum of which was found to be constant at 810 K.
Journal ArticleDOI
Thermal stability of a high surface area ceria under reducing atmosphere
TL;DR: In this paper, the influence of a reducing atmosphere on the thermal stability of CeO2 was studied on a high surface area ceria sample (115 m2 g−1) treated 2 h under hydrogen or carbon monoxide at various temperatures between 673 and 1123 K.
