Temperature-induced structural transition of ceria by bulk reduction under hydrogen atmosphere

Author affiliations

Abstract

Ceria (CeO2) was kinetically reduced in hydrogen depending on the isothermal holding time at high temperature. In situ powder neutron diffraction measurements indicated that ceria underwent structural transition to a triclinic oxygen-deficient structure during the cooling process. Oxygen vacancies were also present in the bulk phase of ceria.
