Abstract: The effects of Pt particle size and vacuum grease on hydrogen spillover were studied by the exchange reaction of deuterium gas with the hydroxyl groups in the system of PtNaY/HY using infrared spectroscopy.
It was found that the smaller the Pt particle size the faster the exchange rate, also the exchange rate can be accelerated by vacuum grease.
The exchange rates at three different temperatures (50 ℃, 100 ℃, 150 ℃)were measured, and the exchange mechanism was discussed.
