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.
