Electronic and Reaction Study of Doped CeO2 with Fe Cations for Hydrogen Production from Water

In this work we present a study of a series of solid solutions of the form of Ce_xFe_1-xO₂ (x<1). Creating neutral oxygen vacancies, results in lattice deformation which in turn decreases the energy needed for the reduction of Ce⁴⁺ (upon the removal of oxygen atoms from the lattice).
