Key Intermediates in the Hydrogenation of Carboxylic Acids on the Pt–ReOx/TiO2 Catalyst
The reactivity of adsorbed acetic acid forms on the Pt–ReOx/TiO2 catalyst has been studied. Three adsorbed acetic acid forms were identified by in situ Fourier IR spectroscopy at 200°С: bidentate acetates and two forms of molecularly adsorbed acetic acid. The consumption rate constants two forms of molecularly adsorbed acetic acid (0.02 and 0.029 s–1, respectively) were found to be close in magnitude to the catalytic reaction constant rate (0.034 s–1) measured at 200°С. It was concluded that these two forms of molecularly adsorbed acetic acid are key intermediates in acetic acid hydrogenation on the Pt–ReOx/TiO2 catalyst.
