چکیده انگلیسی
- The present investigations are successfully introduced a new functionalized surface precursor of urea/Li-Mg powders/γ-Al2O3 as new potential candidate for hydrogen storage with powerful ultra high H2-release capacity â¼6.91 wt% at 340 °C.
- Hydrogen release capacity was enhanced by eliminating defects and lake of surface area caused by released ammonia bi-products.
- Incorporating of mesoporous-γ-Al2O3 trace additions were successful acting as acidic sorbent material for ammonia capture.
- Amidation process (amide forming) via action of urea on Li2 - Mg-alloy which stabilized on surface's of precursor as M-N-H with releasing protons, accompanied with forming MNH2 (where M=Li and Mg) exhibits high desorption (H2-release) capacity of 6.91 wt% at 340 °C which is higher and better than individual Li2Mg-alloy as hydrogen storage matter.
