Hydrogen bronze formation within Pd/MoO3 composites
Article Abstract:
The investigation shows that when H2 is introduced to the Pd/MoO3 composites, it is rapidly absorbed to form internal H-bronzes because of the availability of the mobile H atoms within the Pd matrix. It is concluded that the amount of hydrogen absorbed by Pd/MoO3 composites at low pH2 are much greater than the amounts absorbed by internally oxidized Pd alloys such as Pd-Al(super 3) where the latter composite traps H at the internal Pd/oxide interfaces but does not form a hydrogen bronze.

Influence of cation exchange on M-Pt-ETS-10 molecular sieve: Correlation between ab initio results, catalytic activity, and physiochemical investigations
Article Abstract:
The influence of different alkali metal ions on the activity of Pt-ETS-10 in n-hexane aromatization is reported. The results of ab initio Hartree-Fock calculations on model clusters representing the Pt(active) site, molecular sieve with cations, Pt-M-molecular sieve, benzene, and H2S adsorbed over Pt-molecular sieve are presented.

Isothermal kinetic study of nitric oxide adsorption and decomposition on Pd(111) surfaces: Molecular beam experiments
Article Abstract:
The kinetics of NO adsorption and dissociation on Pd(111) surfaces and the NO sticking coefficient were probed by isothermal kinetic measurements between 300 and 525 K using a molecular beam instrument. The results are discussed with respect to the rate-limiting character of the different elementary steps of the reaction system.
