摘要: Nanoscale Au/Fe2O3 catalysts for CO oxidation were prepared by a deposition–precipitation technique using the thermal decomposition of urea. Freshly precipitated amorphous Fe(OH)3 was used as support. The resulting products characterized transmission electron microscopy and x-ray powder diffraction. in 'as prepared' state demonstrated exceptionally high activity toward oxidation. Compared to conventional coprecipitation with same amount gold precursor, method shown produce more active because it allows complete precipitation from solution.
