Titel:
Dynamic Self-Organization of Supported Pd/Au Catalysts during Vinyl Acetate Synthesis
Abstract:
It is known that vinyl acetate monomer synthesis over bimetallic Pd1Au1 catalysts is highly structurally sensitive and that these structures are dynamically formed and disintegrated in reactant gas atmosphere. Here we show via a combination of bulk and surface sensitive methods that independent of their nominal composition, Pd/Au bimetallic particles undergo marked reconstruction and phase partition during vinyl acetate synthesis. While temperature-induced reorganization of SiO2-supported PdxAuy...     »
