Synergistic effect between Pd and nonstoichiometric cerium oxide for oxygen activation in methane oxidation
Article Abstract:
A study was conducted to analyze the synergistic effect between palladium and nonstoichiometric cerium oxide for oxygen activation in methane oxidation. Catalysts supports were made by impregnating photon-alumina and silica powders with an aqueous solution of cerium(III) nitrate. Experimental results indicated that differences in the behavior of lattice oxygens in cerium oxides correlated with the structure of cerium oxide and employed supports.

Silver bromide as a photocatalyst for hydrogen from CH3OH/H2O solution
Article Abstract:
Photolysis of CH3OH/H2O solution was performed using a AgBr/SiO2 catalyst prepared from Schumann emulsion. UV illumination observations revealed that H2 was generated and hydrogen was continuously produced for 200 h without destroying AgBr. However, X-ray diffraction analysis after the reaction revealed a presence of Ag0. These findings indicate that the production of hydrogen from methanol in distilled water occurs in the Ag0.

Redox properties of nanocrystalline Cu-doped cerium oxide studied by isothermal gravimetric analysis and X-ray photoelectron spectroscopy
Article Abstract:
It has been possible to investigate the thermochemical stability of surface-segregated copper in Cu-doped CeO2 catalysts. It was found that all three oxidation states of copper could be present according to the reduction/oxidation specifications.
