Catalysis by doped oxides.
Eric W. McFarland,Horia Metiu +1 more
TL;DR: The article discusses oxidation catalysis by substitutional cation doping of binary oxides by assuming that the 'as-prepared' catalyst is a doped oxide that, under reducing reaction conditions, is converted to very small metallic dopant clusters supported on the host oxide.

Effect of incorporation of copper or nickel on hydrogen storage in ceria. Mechanism of reduction
TL;DR: In this article, a reduction mechanism, partly based on heterolytic dissociation of H2, is proposed to reduce the amount of hydrogen stored in the host oxide and the reduction of Ce4+ to Ce3+.

Complete oxidation of carbon monoxide and methane over metal-promoted fluorite oxide catalysts
Wei Liu,Wei Liu,Adel F. Sarofim,Adel F. Sarofim,Maria Flytzani-Stephanopoulos,Maria Flytzani-Stephanopoulos +5 more
TL;DR: In this paper, a synergistic reaction model is proposed to explain the enhanced catalytic activity and stability of the Cu-Ce-O binary oxide catalysts, where the dispersed copper clusters may be stabilized by diffusion of copper ions into interstitial metal ion sites of the cerium oxide lattice forming Cu +1 species in the process.
