摘要

近年来，储氢材料的有效释氢引起了人们的广泛关注。在本工作中，CoCl2·6H2O（氯化钴六水合物，CCH）是一种低成本且易于获得的催化剂，成功地用于催化NaBH4-NH3BH3复合物的水解（xSB AB，x是SB与AB的摩尔比）。结果表明，球磨产生的协同效应有利于提高xSB-AB水解的释氢性能。这项工作不仅加深了对SB和AB协同作用的理解，而且为使用低成本催化剂提高xSB AB的水解性能提供了基础

Hydrogen release from hydrolysis of NaBH4-NH3BH3 composite promoted by CoCl2·6H2O

In recent years, the effective hydrogen release from hydrogen storage materials has attracted extensive attention. In this work, CoCl2·6H2O (Cobalt chloride hexahydrate, CCH), a low cost and easily available catalyst, was successfully used to catalyze the hydrolysis of NaBH4-NH3BH3 composite (xSB-AB, x is the molar ratio of SB to AB). The results show that the synergistic effect produced by ball milling is beneficial to improve the hydrogen release performance of xSB-AB hydrolysis. This work not only advances the understanding of the synergistic effect of SB and AB, but also provides a basis for using low-cost catalysts to improve the hydrolysis performance of xSB-AB
