In situ DRIFTS was employed to investigate the reaction of hydrogen with supported subnanometer Pt-ReOx species that are active in the hydrogenation of carboxylic acids. Absorption bands of platinum hydrides in the region of 2025–2043 cm–1 were detected; high reactivity of the hydrides toward the adsorbed acetic acid was revealed. In the process, the absorption band of platinum hydride shifted to high frequencies and increased in intensity due to the influence of adjacent acetates on the electronic state of platinum. It was found that in a hydrogen medium the intensity of platinum hydride bands sharply increases after the adsorption of acetic acid and then gradually decreases owing to the reaction of the hydrides with surface acetates.
