摘要
The application of NaBH4 hydrolysis to hydrogen generation is currently obstructed by its regeneration. Finding a simple and low cost method to regenerate its hydrolysis byproduct is therefore important. Herein, the regeneration of NaBH4 is obtained by reacting its direct hydrolysis byproduct, NaBO2 center dot 2H(2)O, with a mixture of Mg and Mg2Si by ball milling. In this reaction, the reduced agents are only metal and intermetallic compounds, thus hydrogen in the regenerated NaBH4 (H delta-) derives solely from NaBO2 center dot 2H(2)O (H delta+). The introduction of Mg2Si increases the NaBH4 regeneration yield to 86%, which is the highest regeneration yield reported for NaBH4 until now. The reaction mechanism was also clarified for the first time. (C) 2017 Elsevier B.V. All rights reserved.
