Iridium catalysts with the active component content of 10, 20, and 30 wt% on mesoporous aluminosilicate have been synthesized by the reductive hydrolysis of iridium chloro complexes. The degree of dispersion of supported iridium was controlled by increasing the weight percentage of iridium nanoparticles in the catalyst. In this research, it was shown that the crushing strength of the catalysts synthesized on the basis of aluminosilicate with different weight percentages of iridium nanoparticles can be different. The results of hydrazine decomposition show that the performance of the catalysts increases from 10 wt% to 20 wt%, and subsequently, by increasing the concentration of iridium to 30% by weight, with the decomposition parameters remaining constant, the resistance to crushing of the catalyst decreases. The present work is intended to provide some useful correlations between the iridium catalytic activity and the potential parameters in the support materials, and thus making the process more active.
