| Abstract | Hydrogen can be easily produced from the catalytic hydrolysis of sodium borohydride (NaBH(4)), with sodium metaborate (NaBO(2)) being the co-product. If NaBO(2) can be economically recycled in the process, NaBH(4) could be considered as a promising hydrogen carrier in fuel cells because of its high hydrogen content. In this paper, we report our investigation into the synthesis of NaBH(4) from NaBO(2) via ball milling. The starting materials for the synthesis were NaBO(2) and magnesium hydride (MgH(2)). After ball milling at ambient temperature in inert gas, NaBH(4) and magnesium oxide (MgO) were produced. The synthesized NaBH(4) was extracted from the admixture by isopropylamine. Our results indicated that the yield of NaBH(4) from this process was 71 wt.% when the MgH(2)/NaBO(2) mole ratio, ball/powder ratio (BPR), inert gas (argon) pressure, and milling time were 2.07:1, 50:1, 200 kPa, and 2 h, respectively. The mole ratio of the reactants (MgH(2) and NaBO(2)), ball-milling time, BPR, and milling atmosphere were found to have significant influence over NaBH(4) Synthesis. We present the results and discuss the effects of these key parameters in this paper. |
