Background: Hydrogen is considered a clean energy carrier. Ammonia-borane (AB,
NH3BH3) has been attracted considerable attention as a potential chemical hydrogen storage material.
Objective: To improve the catalytic activity for hydrogen production of AB hydrolysis, to develop a
catalyst with high activity is urgently needed.
Method: The patents relating to the catalytic hydrolysis of AB for hydrogen production are reviewed.
We successfully synthesized ginkgo leave-derived carbon by pyrolysis and chemical activation. Then,
ruthenium particles were supported on this porous carbon (Ru/GC) by in situ reduction.
Results: The as-prepared Ru/GC catalysts for AB hydrolysis exhibit high activity (TOF = 921
-1·min-1) and low activation energy (Ea = 23.86 kJ·mol-1). Moreover, fairly good recyclability
with 58% of the initial catalytic activity is retained after five cycles.
Conclusion: The high catalytic performance and easy preparation demonstrate that Ru/GC is a highly
efficient catalyst towards AB hydrolysis.
