Cerium(IV) oxide used as a mixed conductor. Ceria is of interest as a material for solid oxide fuel cells (SOFCs) because of its relatively high oxygen ion conductivity (i.e. oxygen atoms readily move through it) at intermediate temperatures (500–650 °C) and lower association enthalpy compared to Zirconia system. The cerium(IV) oxide–cerium(III) oxide cycle or CeO/CeO cycle is a two step thermochemical water splitting process based on cerium(IV) oxide and cerium(III) oxide for hydrogen production. Cerium(IV) oxide Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a
Dihydrogen bond via dihydrogen bonding. This kind of H−H interaction is distinct from the H−H bonding interaction in transition metal complexes having dihydrogen bound to a metal. So-called hydrogen hydrogen bond interactions have been proposed to occur between two neutral non-bonding hydrogen atoms from Atoms in molecules theory, while similar interactions have been shown to exist experimentally. Many of these types of dihydrogen bonds have been identified in molecular aggregates. Dihydrogen bond In chemistry, a dihydrogen bond is a kind of hydrogen bond, an interaction between a metal hydride bond and an OH or NH group or other proton donor. With a
