ZnCl2 + 2NaBH4 → Zn(BH4)2 + 2NaCl (1) Zn(BH4)2 powders were characterized by X-ray diffractometry(XRD), and Furier Transform Infrared spectrometry(FT-IR). The thermal stabilities of Zn(BH4)2 powders were studied by Differential scanning calorimetry(DSC), Thermogravimetry analysis(TGA), and Mass spectrometry(MS). Zn(BH4)2 can be tested for hydrogen evolution without further purification. The reaction to yield hydrogen is irreversible, the other products being compounds of Zn, and borane. Zn(BH4)2 thermally decomposes to release borane and hydrogen gas between about 85 and 150 ℃ 한국수소및신에너지학회 Zn[BH4]2 분말의 합성과 열분해 특성 Synthesis and Thermal Decomposition ofZn[BH4]2 Article 2 한국수소및신에너지학회논문집, v.16, no.3, pp.262 - 268 한국수소및신에너지학회논문집 16 3 262 268 kci other ART000972237 zinc borohydride complex metal hydride hydrogen storage material mechanochemical reaction thermal decomposition
