AbstractThe temperature-programmed desorption of hydrogen from a Pt/TiO2 catalyst reduced in a wide temperature range (RT-773 K) has been studied. It is found that the presence of labile surface oxygen species increases the amount of hydrogen species formed at room temperature, and greatly decreases the quantities of adsorbed hydrogen species at medium temperatures. After the catalyst was reduced at high temperature, it is observed that two strong hydrogen desorption peaks appear at 450-600 K and above 600 K, which are ascribed to surface titanium hydride and the hydrogen species stored in the sublayer and bulk of the support, respectively.
