Recombination pathways in the Degussa P25 formulation of TiO(sub 2): Surface versus lattice mechanisms
Article Abstract:
The charge migration between electron trapping sites within the mixed-phase titania photocatalyst Degussa P25 was studied. The findings indicate that in mixed-phase TiO(sub 2) such as Degussa P25, photogenerated holes are trapped exclusively on the particle surface, while photogenerated electrons are trapped within the nanoparticle lattice.

Pyrrole as a probe molecule for characterization of basic sites in ZSM-5: A combined FTIR spectroscopy and computational study
Article Abstract:
The interaction of pyrrole with alkali metal ion exchange ZSM-5 is studied. The computational hybrid quantum mechanics/ interatomic potential function method describing the role of the aluminum framework content and aluminum distribution, pyrrrole coverage, cation size, and cation coordination type is presented.
