The catalytic performance of Au/Al 2 O 3 catalyst is highly sensitive to preparation procedure. EXAFS and TEM characterization of key steps in the preparation in conjunction with activity measurements result in deeper insights into precautions needed

Gold catalysts supported on γ-Al2O3 (Au/γ-Al2O3) were prepared by deposition-precipitation of aqueous HAuCl4 and, alternatively, by deposition of Au(CH3)2(acac) from pentane solution. The samples were characterized by in situ XANES and temperature-

Supported Au catalysts are very active for low temperature CO oxidation. However, the reported activity from different laboratories for apparently similar catalysts can differ quite substantially. Recent progress in resolving this difficulty is summa

Supported Au catalysts are generally prepared from chloride-containing Au precursors and their properties are highly sensitive to preparation procedures. To better understand and control the variables important in the preparation of these catalysts,

Simultaneous catalytic removal of NOx, SOx, and CO under simulated FCC regenerator conditions was investigated over mixed oxide catalysts CuMgAlO (Cu-cat), CeMgAlO (Ce-cat), and CuCeMgAlO (CuCe-cat), which were prepared by coprecipitation and charact

The deactivation and regeneration phenomenon during room temperature CO oxidation was studied over a Au/γ-Al2O3 catalyst, which was as active as the most active supported Au catalysts reported in the literature. The initial rapid loss of activity co

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and
