摘要
In this study, the effect of multi-walled carbon nanotubes （MWCNTs） additive on the dehydriding properties of the Zn（BH4）2/NaCl 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 ZnCl2 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.
