Denkwitz, J. Geserick, U. Hörmann, V. Plzak, U. Kaiser, N. Hüsing, R. Behm] The activity and stability of structurally well defined mesoporous Au/TiO2 catalysts with different support morphologies and pore sizes for low temperature CO oxidation was investigated by kinetic measurements and in-situ IR spectroscopy. The resulting catalysts with Au particle sizes of ∼3nm exhibit a high activity for CO oxidation, similar to or exceeding that of highly active standard Au/TiO2 catalysts with similar size Au nanoparticles and loading, and a significantly lower tendency for deactivation. Possible reasons for the improved performance of these catalysts are discussed.
