Supported binary CuO _x -Pt catalysts with high activity and thermal stability for the combustion of NH₃ as a carbon-free energy source.

ABSTRACT: Recently, NH₃ has been thought to be a renewable and carbon-free energy source. The use of NH₃ fuel, however, is hindered by its high ignition temperature and N₂O/NO production. To overcome these issues, in this study, the combustion of NH₃ over copper oxide (CuO _x ) and platinum (Pt) catalysts supported on aluminium silicates (3Al₂O₃·2SiO₂), aluminium oxides (Al₂O₃), and silicon oxides (SiO₂) were compared. To achieve high catalytic activity for the combustion of NH₃ and high selectivity for N₂ (or low selectively for N₂O/NO), conditions for the preparation of impregnated binary catalysts were optimised. With respect to the binary
