In this experiment, the different raw material is used for synthesis 𝞬-Al2O3 catalyst base using the oildrop route. Aluminium nitrate (Al(NO3)3), Aluminium Chloride (AlCl3), Boehmite (AlOOH), Aluminium Isopropoxide (C9H21O3Al) and Aluminium Acetate are used as precursor. After dry The granules, calcination is done at 450℃ and 750℃. To analyze the physical and chemical properties, X ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), optical microscopy (OM), thermal analyses (STA), BET and crush strength test are used. Based on XRD analyses and utilizing pre-materials, 𝞬- Al2O3 phase is observed in all samples. 𝞬-Al2O3 granules with mechanical strength from 3.3 to 90.8 are obtained. Specific surface area, volume and the diameter of porous granules obtained in order from various precursors is 196.23 to 381.9 m2/g, 3.96 to 16.8 nm, 0.29 to 1.24 cm3/g. By using the obtained granoles as a catalyst base, active Iridium metallic catalyst is made and analyze employing the Hydrazine decomposition test. The 20 wt % iridium catalyst with catalyst support created from aluminum nitrate precursor had the best result in the decomposition test of hydrazine monohydrate because without any crushing of the granules, the highest efficiency occurred in the decomposition of hydrazine monohydrate.
