摘 要：<正>In this study,the effect of multi-walled carbon nanotubes（MWCNTs） additive on the dehydriding properties of the Zn（BH4）2/NaCI composite prepared by high energy ball milling were investigated.X-ray diffraction（XRD）,Fourier transform infrared spectroscopy（FTIR） results demonstrated that Zn（BH4）2 was produced from mechanochemical reaction between ZnCI2 and NaBH4.Compared with the undoped sample,10 wt% MWCNTs effectively lowered the decomposition temperature of Zn（BH4）2 by 15℃.The complex released 3.6 wt%hydrogen within 250 s at 100℃and totally released 4.5 wt%hydrogen within 2500 s,indicating it has a considerable potential as a hydrogen storage material.
