Ultra high loading iridium catalyst, 30 wt% for hydrazine decomposition reaction was developed. The catalyst was prepared successfully with the multiple impregnation methods to make nanoparticles of which the size was in the range of 2-3 nm. The X-ray diffraction of the catalyst indicated the surface was covered fully with iridium metal. The transmission electron micrograph of the catalyst showed the uniform distribution of the Ir particles of 2-3 nm in size over the support. The result of the hydrogen chemisorption more than 0.3 mmol per gram catalyst was consistent with the formation of nanoparticle even for such high metal content. |
