Synthesis of CuO nanoribbon arrays with noticeable electrochemical hydrogen storage ability by a simple precursor dehydration route at lower temperature

CuO nanoribbon arrays were synthesized by a simple dehydration reaction for the first time. The products exhibit excellent hydrogen storage capacity and big BET surface area. The present work shows that the nanostructures of products are important to their electrochemical hydrogen storage performances. Further research will be performed on more novel cupreous 1D nanoarrays exhibiting different electrochemical hydrogen storage performances, in which more excellent hydrogen storage materials might be found. On the other hand, the low cost, convenient process, good reproducibility, high yield, and clean reactions of the present synthetic method make it possible to scale it up to industrial production.
