Abstract

Mechanochemical reactions between KBH4 and KBF4 result in the formation of potassium fluoroborohydrides K(BHxF4−x) (x = 0–4), as determined by 11B and 19F solid state NMR. The materials maintain the cubic KBH4 structure. Thermogravimetric (TG) data for a ball-milled sample with KBH4 : KBF4 = 3 : 1 are consistent with only desorption of hydrogen.
