This issue was brought to our attention by the editorial board on behalf of the
authors of the above paper and we wish to express regret for not including it
in the list of references. We were aware of this work during our research and
the citation was indeed included in earlier versions of the manuscript during
its preparation. Unfortunately, the reference was accidently removed during
subsequent revisions, and this oversight has been carried over into the
published paper.
The study by Pistidda et al. reports the
synthesis of Mg(BH4)2 exclusively by reactive ball
milling of MgB2 at room temperature under 100 bar of hydrogen and
characterization of the obtained amorphous product via NMR. This work should
have been cited along with references 8a-c in the introduction section. The
results reported by Pistidda et al. agree well
with some of the data in Figure 2 of our paper and this fact should have been
duly acknowledged in the discussion of this figure. We have further examined
the effects of hydrogen pressure, milling time, and milling energy (as ball to
sample ratio) onto the reaction progress, intermediate species, and final
products. Based on these analyses we have tried to provide detailed insights
into the reaction mechanism. We also demonstrated the possibility to regenerate
the dehydrogenated product through reactive milling.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
