A study of the effect of the addition of nanostructured carbonaceous catalysts in the dehydrogenation mechanism of magnesium borohydride

Abstract

The combined addition of carbonaceous catalysts with titanium decreases significantly the energy cost for H-removal from magnesium borohydride.

LiAlH4 as a “Microlighter” on the Fluorographite Surface Triggering the Dehydrogenation of Mg(BH4)2: Toward More than 7 wt % Hydrogen Release below 70 °C

“…Carbon materials with novel structures have been utilized in tailoring the dehydrogenation behaviors of Mg­(BH 4 ) 2 . , Chen et al successfully achieved a nanosized layer coating of Mg­(BH 4 ) 2 on the surface of carbon nanotubes (CNTs) . According to the report, 50Mg­(BH 4 ) 2 -CNTs hybrid starts to release hydrogen at 76 °C, and 3.79 wt % hydrogen can be liberated in 10 min at 117 °C.…”

A DFT study on the hydrogen desorption from the lithium borohydride and aluminohydride upon the addition of nanostructured carbon catalyzing agent

“…Studies on the use of carbon nanomaterials as catalysts in conjunction with complex metal hydrides showed remarkable properties [19][20][21]. For instance, the buckminsterfullerene C 60 has proved to be an excellent catalyst for hydrogen desorption when added to Mg(BH 4 ) 2 , NaAlH 4 , LiAlH 4 and LiBH 4 [22][23][24]. A fullerene-LiBH 4 composite demonstrates remarkable catalytic effect [25].…”
