文摘
- •
Ammonia borane was loaded in four supports: two mesoporous silicas, GaO3 and CoAPO-5.
- •
Nanoconfinement of ammonia borane facilitates hydrogen release at lower temperatures.
- •
The formation of gaseous BNHx fragments was also reduced by nanoconfinement.
- •
Polyiminoborane was not formed during thermolysis of AB loaded in mesoporous silica.
