Hydrogen production from hydrolysis of NaBH4-NH3BH3 composite catalyzed by porous spherical Co3O4
NaBH4-NH3BH3 composite (xSB-AB, x is the molar ratio of SB to AB) has better hydrolysis performance than its monomer, but the hydrogen generation rate (HGR) and hydrogen yield (HY) are still not ideal at room temperature. In this work, a low cost and easily available commercial porous spherical Co3O4 was successfully used to catalyze the hydrolysis of xSB-AB composite. It was found that Co3O4 showed good catalytic performance for the hydrolysis of xSB-AB, and the HY and hydrogen release efficiency (HRE) of 4SB-AB/10 wt%Co3O4 at 40 ℃ reached 2,279.71 mL·g-1 and 89.13%, respectively.
