Research Abstract

Gold acts as catalyst for CO oxidation even below room temperature when it is supported on specific metal oxides in the form of nanoparticles. Having combined atomic resolution environmental transmission electron microscopy, catalyst chemistry and ab-initio computation, we performed the atomistic and electronic analyses on the morphology and the atomistic structure of gold nanoparticles, the adsorption sites of CO and the activation sites of O2at the reaction conditions. Furthermore, we succeeded in visualizing gas molecules that were adsorbed in metal nanoparticles at the reaction conditions.
