This work presents the study of the catalytic activity of aluminum oxide supported Co-Schiff Base complex derived from 4,4'-Methylenebis(2,6-diethylaniline)-3,5,-itertbutylsalicylaldimine-Co-Schiff Base complex in sodium borohydride hydrolysis. This catalyst is characterized with XRD, FT-IR, SEM, TEM, and BET. The respective reaction kinetics have been calculated. With the catalyst condition, maximum reaction (initial) rate is 106540 and 147193,3 mL H-2/g(cat). min. at 30 degrees C and 50 degrees C. For this reaction apparent activation energy is 44,7792 k.J mol(-1) with 20-50 degrees C. The reaction order value (n) for this catalytic system is 0,31. Additionally when Al2O3 supported Co-Schiff Base complex compared with pure Co-Schiff Base complex, the experimental results show that the aluminum oxide support exhibits enhancing effect with 106540 and 64147 mL H-2/g(cat ) min respectively in sodium borohydride hydrolysis to Hydrogen production.
