摘要

Abstract

The efficient and cost-effective implementation of ammonia borane (AB) hydrolysis dehydrogenation for hydrogen storage is crucial. This study investigated the role of solid acid Amberlyst-15 (A-15) for hydrogen evolution from AB hydrolysis. Notably

AB hydrogen evolution rate can reach 194.15 ml·min

-1

at 30℃

with a low apparent activation energy of 8.20 kJ·mol

-1

. After five cycles of reuse

the reaction involving A-15 could keep a conversion rate of about 93%. The AB hydrolysis follows quasi first-order kinetics with respect to the AB concentration and quasi zero-order kinetics with respect to the A-15 mass. According to the characterization results of XRD

ATR-FTIR

and in-situ MS

the boric acid was the dominant hydrolyzate

while water as a hydrogen donor in this reaction. Furthermore

based on the reasoning that hydrogen bonds between A-15 and AB (aq) promotes the diffusion of AB

release of H

and the cleavage of OdH bond of H

a possible mechanism was proposed.
