Gold nanoparticle catalysts for the direct epoxidation of propylene were studied. The hydrogen oxidation over gold was used as a probe reaction for the catalytic activity of the gold nanoparticles. Propylene adsorbed strongly on gold under reaction conditions typical for the hydro-epoxidation of propylene. Under propylene hydro-epoxidation reaction conditions, propylene was absorbing on gold nanoparticles. Propylene adsorption decreased the hydrogen oxidation rate and interacted with surface gold atoms. This is an abstract of a paper presented at the AIChE Spring National Meeting (New Orleans, LA 4/6-10/2008).
