| 英文摘要 | mg(nh2)(2)-2lih is an attractive system because of its high reversible hydrogen capacity (similar to 5.6 wt%) and suitable thermodynamic parameters that allow operation below 100 degrees c. however, a relatively high kinetic barrier in the hydrogen desorption blocks its application at low temperature. in this work, a small amount of additive, triphenyl phosphate (tpp), was introduced and its effects on hydrogen desorption/absorption in the mg(nh2)(2)-2lih system were studied. experimental results showed that tpp can prevent aggregation/crystallization during the cycling tests and thus achieve an enhanced kinetic performance. complete dehydrogenation and hydrogenation can be successfully carried out at temperatures below 150 degrees c. moreover, a significant reduction of the entropy change of hydrogen desorption (dsdes) was found in the tpp-doped system compared with the pristine mg(nh2)(2)-2lih system, thought to be due to the persistence of amorphous mg(nh2)(2) in the tpp-doped sample during dehydrogenation and hydrogenation cycling, thereby greatly affecting the equilibrium hydrogen pressure. |
