Abstract:
The utilization of NH۳BH۳ (ammonium borane) as a H۲ gas storage compound is restricted by its slow rate for H۲ evolution. In this study, three Ag@Zn-MOF nanocomposites with different amounts of Ag:Zn-MOF ratio of ۰.۲۵:۱ (۱), ۰.۵:۱ (۲), and ۱:۱ (۳) were investigated as catalysts for hydrogen evolution from hydrolysis of NH۳BH۳. Well dispersed encapsulated Ag nanoparticles (۳۰-۶۰ nm) in the matrix of the composites have been prepared in the presence of Zn(II) metal-organic frameworks (Zn-MOFs) in an aqueous solution by using NaBH۴ as a reducing agent at room temperature. These nanocomposites have shown good catalytic activity for the hydrolysis of NH۳BH۳.
