摘要: Abstract In this study, we report the results of a kinetic study on hydrogen (H2) generation from hydrolysis ammonia borane (NH3BH3) catalyzed by Platinum supported carbon nanotube-graphene hybrid material (Pt/CNT-G). Synthesized catalyst was characterized TGA, XRD, CP-OES, TEM and SEM-EDX techniques. Characterization studies have shown that CNT-G support provides desired distribution Pt particles material. The effect various parameters such as loading, reaction temperature, NaOH NH3BH3 concentration are also determined. Experimental showed Pt/CNT-G exhibited high catalytic activity to release H2. It has been found shows low activation energy 35.34 kJ mol−1 for NH3BH3. with turnover frequency (TOF) 135 (molH2/molcat.min). Therefore, synthesized is potential candidate enhanced H2 through hydrolysis.
