Abstract

Gold nanoparticle catalysts for the direct epoxidation of propene are investigated. The adsorption of propene on the gold nanoparticles is studied using both catalytic experiments and by in-situ XANES analysis. The hydrogen oxidation over gold is used as a probe reaction for the catalytic activity of the gold nanoparticles. Both the hydrogen oxidation experiments and the XANES conclusively show that propene adsorbs strongly on gold under reaction conditions typical for the hydro-epoxidation of propene. It is currently being investigated how this adsorption fits into the epoxidation mechanism of the gold-titania based catalysts.
