Study on Hydrogen Generation from Al−Li/NaBH4 Mixture in Pure Water for Portable Fuel Cell
Solid-state Al−Li/NaBH4 mixtures with salts have been fabricated for hydrogen evolution through a milling process, providing uniform dispersion of metals Al, Li and salts among pulverized NaBH4 particles, in order to increase the contacts of NaBH4 with active catalytic sites. The results show that the mixture has good hydrolysis properties, especially that Al−Li−CoCl2/NaBH4 mixture has hydrogen yield of 1482 mL g-1 in 40−minute hydrolysis in pure water, with 100% conversion efficiency. The catalytic effect comes from Al(OH)3 and Ni2B or Co2B, which were fabricated in the hydrolysis process.
