In the presence of Cu-Schiff Base complex which we reported in advance [1] and with titanium dioxide supports a novel catalyst named TiO2 supported 4-4'-Methylenbis (2,6-diethyl)aniline-3,5-di-tert-buthylsalisylaldimine-Cu complex is prepared, successfully. The synthesized catalyst was characterized by means of X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Brunauer-Emmett-Teller Surface Area Analysis (BET) and Fourier Transform Infrared Spectroscopy (FT-IR). The as prepared catalyst was employed to generate hydrogen through hydrolysis reaction of NaBH4. Effects of different parameters (e.g. amount of Cu-Schiff Base complex in all catalyst, percentage of NaBH4, percentage of NaOH, amount of TiO2 supported Cu-Schiff Base complex catalyst and different temperatures) are also investigated. A high apparent activation energy (Ea), 25,196 kJ.mol(-)1 is calculated for hydrolysis of NaBH4 at 20-50 degrees C. Hydrogen generation rate was 14,020 mL H-2/g(cat).min and 22,071 mL H-2/g(cat).min in order of 30 degrees C and 50 degrees C. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
