چکیده
|
The utilization of nh3bh3 (ammonium borane) as a h2 gas storage compound is restricted by its slow rate for h2 evolution. in this study, three ag@zn-mof nanocomposites with different amounts of ag:zn-mof ratio of 0.25:1 (1), 0.5:1 (2) and 1:1 (3) were investigated as catalysts for hydrogen evolution from hydrolysis of nh3bh3. well dispersed encapsulated ag nanoparticles (30-60 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 nabh4 as a reducing agent at room temperature. these nanocomposites have shown good catalytic activity for the hydrolysis of nh3bh3.
