Abstract

Co2B catalyst was milled with Al and Li to form Al-Li-Co2B composite, and the hydrogen generation performance of Al-Li-Co2B/NaBH4 system was investigated in this study. 100% hydrogen yield was reached, and high hydrogen generation rate was regulated by optimizing the composition design and preparation technology. The improvement was attributed to the synergetic effect of Co2B and Li in the preparation process, whereas a large specific surface area was obtained with the increase in Li content, Co2B, and milling time. In addition, the catalytic activity of Co2B and LiOH from Li hydrolysis was heightened for the hydrolysis of the Al/NaBH4 system because of the addition of Al(OH)3, LiAl2(OH)7.xH2O, and NaBO2 in the hydrolysis process.
