In-situ Raman Spectroscopic Monitoring of Ball Milling Preparations of Amidoboranes

Recently, a few techniques that allow in-situ monitoring of ball milling reaction in real time are developed and well established.[1] For the first time, we applied one of these techniques, Raman spectroscopy, in order to follow up the mechanochemical synthesis of materials for solid-state hydrogen storage. Specifically, a series of single- and bimetallic amidoboranes of MAB, MAB·AB and M2MgAB4 (M = Li, Na ; AB = NH3BH3) composition were prepared and thoroughly characterized. A detailed analysis of spectral data revealed that in all cases a two step mechanism takes place through MAB·AB adducts as a key intermediate phase.
