Cover Story: Sodium borohydride has largely been studied as a hydrogen storage material due to its significant advantages. This work studies the effects of non-toxic and environmentally friendly additives for the hydrolysis process in terms of yield, lag time, hydrogen generation rate, and gravimetric density. Sodium carboxymethylcellulose, polyacrylamide, sodium dodecyl sulfate, and β-cyclodextrin were studied for their application in the storage and release of hydrogen. The best results were provided by the use of sodium carboxymethyl cellulose and polyacrylamide. In the first case, a hydrolysis yield of 85%, a lag time of 70 s, a hydrogen production rate of 1374 mL·min−1·gcat−1, and a storage capacity of 1.8 wt% were obtained. Using polyacrylamide as an additive, a hydrolysis yield of almost 100% was achieved, although it required a significantly higher time period for complete conversion. View this paper
