摘要
Hydrogen energy has attracted considerable attention as a promising alternative to petroleum. Herein, a novel (Al-x%Li)-y%NaBH4 composite with a core-shell structure has been designed and synthesized by a one-step ball-milling method for generating hydrogen by hydrolysis. NaBH4 formed a surface coating that completely wrapped the Al-x%Li alloy particles to prevent agglomeration and oxidation. Meanwhile, the synergism between the Al-Li alloy and NaBH4 promoted the hydrogen generation rate (HGR) of the composite. The total hydrogen release content of (Al-10%Li)-10%NaBH4 reached 1468.8 mLmiddotg-1, with the highest HGR reaching 4393.7 mLmiddotg-1middotmin-1 at 303 K. The (Al-x%Li)-y%NaBH4 composites also exhibited outstanding hydrolysis capacity during reaction with a near-stoichiometric amount of added CoCl2 solution. The hydrogen emission exceeded 90% when only twice the amount of stoichiometric CoCl2 solution was injected. The hydrogen mass density of the total system increased to more than 2.3 wt% from approximately 0.6 wt% with the addition of 10 stoichiometric solution, indicating the practical application of the portable fuel cell in conserving the total volume of the facility.(c) 2022 Elsevier B.V.
