This assay investigates the Co-Cr-B catalyst effect supported on gamma-Al2O3 to produce hydrogen (HG) from ammonia-borane hydrolysis (ABH). For characterization of this catalyst, SEM-EDX, XRD, FTIR and BET surface area analysis were performed. The maximum hydrogen generation rate (HGR) with this catalyst used for the ABH was 3260 ml min(-1) g(catalyst)(-1). The recyclability tests for the Co-Cr-B/gamma-AlO3 catalyst on the ABH have maintained an activity of 68% even after four hydrolysis treatments. Also, the activation energy (Ea) obtained using the Co-Cr-B catalyst supported on gamma-AlO3 for the ABH was 56.06 kJ/mol.
