The hydrogen spillover effect of Pt-NaY/HY system has been studied using the exchange reaction of deuterium with hydroxyl groups by IR spectroscopy. The Pt-NaY catalyst used was prepared by impregnation of NaY zeolite with chloroplatinic acid. HY zeolite was prepared by NH_4~+ exchange of the same NaY zeolite followed by thermal decomposition. About 12.5% Pt metal dispersion and a Pt particle size of about 9.0 nm were determined from H_2 Chemisorption data at 0 ℃.
The wafer of HY zeolite used in the IR cell was mixed with a small amount of the catalyst in such a way that the Pt catalyst dispersed only around the periphery of the wafer.
