Abstract

Adsorption and temperature-programmed desorption of NO was studied over Pt/alkali zeolites. Platinum clusters of three different sizes were prepared by different decomposition routes of [Pt(NH<sub>3</sub>)<sub>4</sub>]<sup>2+</sup> partially ion-exchanged in NaX zeolite. The effect of various alkali ions (Li, Na and K) was also examined. Similarly to platinum supported by alumina, the conversion of adsorbed NO to nitrogen increases with increasing Pt particle size. Increasing electropositivity of the alkali cations shifts the desorption to lower temperatures. <p>
