英文摘要: A series of Pt/gamma -Al2O3 catalysts with different content of Pt were characterized by using low-temperature FT-IR spectroscopy of adsorbed GO, while their catalytic activity for HDS was investigated with thiophene as a model substrate. On the basis of the experimental results, it has been obtained that the pseudo zero order rate of the thiophene HDS reaction is well linearly proportional to the total area of the two IR bands at 2 080 and 1 850 cm(-1) of CO adsorbed on Pt/gamma -Al2O3, and that the Pt sites for CO adsorption may be the active centers for thiophene HDS reaction.
