摘要

The matrix-isolation and laser-induced fluorescence techniques have been employed to study the production of transient species from the oxidation of H₂ on Pt. The excitation of oxidation products trapped in Ar matrices at 10 K with a frequency-doubled dye laser operating at 319 nm resulted in a strong fluorescence at 340 nm. indicating the presence of the OH radical. The variation of the Pt catalyst temperature from 675 to 860°C gave rise to an activation energy of 41 ± 4 kcal/mole for the production of OH from the P± surface.
