Abstract

Platinum was deposited into beta zeolites with different techniques. Platinum was well-dispersed when the catalyst was prepared by ion exchange and Atomic Layer Epitaxy (ALE) deposition methods. In impregnation, the source material of platinum and post-treatments affected for the dispersion. Platinum dispersion was low when trimethyl(methylcyclopentadienyl)platinum impregnated beta zeolite was calcined prior to reduction. In calcination at 623 K in air most platinum was reduced. Platinum was totally reduced with hydrogen at 573 K. In pulsing of carbon monoxide at 300 K on platinum ALE catalyst, carbon dioxide formation was observed. Trimethyl(methylcyclopentadienyl)platinum impregnated beta zeolite produced selectively cinnamyl alcohol at low conversion whereas with other catalysts several different products were formed.
