Abstract

(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.
