Advanced H2-storage system fabricated through chemical layer deposition in a well-designed porous carbon scaffold

Journal Article


Abstract


  • A new and effective in situ impregnation/deposition technique of chemical layer deposition (CLD) on a gas-solid interface is developed for fast and controllable film deposition and functional nanostructure design. Using CLD, a series of nanostructured Al(BH4)3(NH3) 6@porous carbon composites are successfully produced, and a significant improvement of the hydrogen storage properties of Al(BH 4)3(NH3)6 is achieved with tunable dehydrogenation temperature ranging from 114 to 175 ��C, enhanced dehydrogenation kinetics with a low activation energy of 65.6 KJ mol -1 compared to 105.5 KJ mol-1 for the bulk counterpart, and a significantly increased H2 purity from 67.4% to 93.5%. �� the Partner Organisations 2014.
