摘要：

Porous gamma-Al2O3 support with improved mechanical strength was synthesized via sol gel method in granular form having different mesh sizes i.e., 0.60-1.0 mm and 2.0-2.8 mm, followed by rehydration at room temperature and calcination at 1023 K, and was employed for the preparation of Ir and Ru catalysts by impregnation method. The structural features of supports, Ir/gamma-Al2O3 and Ru/gamma-Al2O3 catalysts were characterized by N-2 physiosorption, H-2 chemisorption, crushing strength measurements, XRD, SEM, and TEM. The catalytic activity was evaluated for hydrazine decomposition in a 1 N microthruster at ambient temperature. (C) 2014 Elsevier BAT. All rights reserved.
