摘要
(Figure Presented) Support system: The stability of a LaPO 4-supported Au nanocatalyst for CO oxidation exceeds that of Au nanocatalysts with oxide supports. Activation is achieved by high-temperature calcination under an oxidative atmosphere (see transmission electron microscopy image of crystalline Au nanoparticles on hexagonal LaPO4). The use of phosphates as supports for highly active gold catalysts opens up new routes in the search for ultrastable and sinter-resistant catalysts. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
