Investigation of Hydrogen Production from Sodium Borohydride in the Presence of Ni/Al₂O₃

Abstract With the increasing trend towards use of renewable energy and encouragement international agreements due to environmental effects, world tends provide it needs from sources. Hydrogen is an environmentally friendly carrier that produced various sources can be a sustainable solution needs. Catalyst evaluation studies are carried out in release high purity hydrogen by hydrolysis metal hydrides such as sodium borohydride (NaBH 4 ), potassium (KBH ). In this study, Al 2 O 3 supported Ni catalysts were synthesized impregnation method characterized applying X-Ray Diffractometry (XRD), Fluorescence (XRF), Scanning Electron Microscopy (SEM), Brunauer-Emmett-Teller (BET) methods. The performance was evaluated production borohydride. influences reaction temperature (20, 40, 60 °C) content catalyst 30, 40 %) on investigated under experimental conditions 100 mg NaBH , catalyst, 5 mL 0.25 M NaOH. highest yield (100%) rate (364.3 mL/g cat .min) obtained with 40% Ni/Al at °C temperature.
