Photoprocesses in AOT reverse micelles containing metalloporphyrins and oligopeptides
Article Abstract:
Ground-state absorption spectra of Pd(II)TMPy(super 4+) and Pd(II)TMPy(super 4+) in AOT-heptane-H2O reverse micelles indicated that electrostatic interactions of a tetracationic porphyrin with surfactant polar head groups play a key role in determining the localization of the porphyrin molecules in reverse micelles. Flash photolysis experiments showed that, in the presence of peptide in aqueous solution, Pd (II) TMPy (super 4+) triple-state decay is strictly monoexponential.

Comment on "combined in situ infrared and kinetic study of the catalytic CO + NO reaction on Pd(111) at pressures up to 240 mbar"
Article Abstract:
The position of the absorption band of NCO formed in the dissociative adsorption of HNCO and in the high-temperature reaction of NO + CO over supported Pd was determined. In first experimental series the NCO species was produced by HNCO adsorption. Exposure of silica-supported Pd to HNCO at 200-300 K produced an intense band at 2264 cm(super ~1), a less intense one at 2183 cm(super -1, and very weak one at 2305 cm(super -1).

Combined in Situ infrared and kinetic study of the catalytic CO + NO reaction on Pd(111) at pressures up to 240 mbar
Article Abstract:
Infrared spectroscopy is used to examine in situ adsorption behavior and kinetics of CO + NO reactions. Isocyanate plays the role of a spectator instead of an intermediate in the CO + NO reaction.
