摘要

NaBH4-NH3BH3复合材料（xSB-AB，x为SB/AB的摩尔比）具有比其单体更好的水解性能，但在室温下的产氢速率（HGR）和产氢率（HY）仍然不理想。在这项工作中，一种低成本且易于获得的商业多孔球形Co3O4成功地用于催化xSB-AB复合材料的水解。结果表明，Co3O4对xSB-AB的水解具有良好的催化性能，4SB-AB/10wt%Co3O4在40℃时的HY和释氢效率分别达到2279.71mL·g-1和89.13%。

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.
