| Popis: | Nitrogen-doped ordered mesoporous carbon has been synthesized and used to confine LiBH4 to improve its dehydrogenation properties. The carbon has a high BET specific surface up to 448.25 m2/g with pore size centered at 1.2 and 4.1 nm. The effects of ball milling time and speed on de-hydrogenation were investigated. The onset hydrogen desorption temperature of LiBH4 is reduced to 100 °C by addition 40 wt% carbon, and it can release hydrogen of 8.3 wt% at 380 °C. Furthermore, cyclic dehydrogenation is studiedto estimate the stability of the samples in the present work. |
