▎ 摘  要

Developing highly efficient and stable supported bimetallic nanoparticles catalysts via a facile strategy is one of the most admirable methods for sustainable hydrogen production from borohydride hydrolysis. Herein, we developed a facile technology for rapidly and straightforwardly manufacturing Pt-Ni bimetallic nanoparticles (BNPs) supported by partially reduced graphene oxide (prGO) with excellent catalytic activity and outstanding durability for hydrogen production from KBH4 and NH3BH3 alkaline solution. The uniformly dispersed Pt-40-Ni-60 BNPs with a statistical size of around 2.6 nm exhibited a surprising catalytic activity of 23,460 mol-H-2.h(-1).mol-Pt-1 at 308 K, moreover, whose activity was high up to 80% of the first time even after 30 runs, demonstrating an outstanding stability. The apparent activation energy for dehydrogenation of KBH4 and NH3BH3 were respectively about 27.8 and 33.6 kJ/mol for the prepared Pt-40-Ni-60/prGO catalyst. The extraordinary catalytic activity of the Pt-40-Ni-60/prGO catalyst owing to the strong charge transfer effect between Pt-Ni BNPs and graphene.& nbsp;(c) 2022 Hydrogen Energy Publications LLC.
