Abstract

Neutron diffraction measurements revealed that the oxyhydroxide ceria CeO₂H_y (0 ≦ y ≦1) was formed by the interaction of hydrogen under high temperature. Ceria was kinetically reduced in hydrogen depending on the isothermal holding time, and the crystal phase of CeO₂H was precipitated during the short isothermal holding time.
