Influences of Ir precursors on the catalytic performances of Ir/γ-Al(2)O(3) nanocatalyst

Iridium supported on gamma alumina nanocatalysts have been prepared by incipient wetness impregnation with two different precursors: H(2)IrCl(6).xH(2)O and IrCl(3). This research aims to increase the activity of Ir/γ-Al(2)O(3) nanocatalysts for hydrazine decomposition. The phase structures, particle sizes, distribution, and the morphology of reduced nanocatalysts were determined by means of X-ray diffraction (XRD), and Scanning electron microscopy (SEM).
