用透射电镜和电子能量损失谱（EELS）原位观察了高能电子辐照诱导α-AlH 3的放氢反应。α-AlH 3晶体分解成细小的铝颗粒，同时由于覆盖整个颗粒的薄刚性表面层而保持其初始外部形状。EELS表明，薄的表面层是无定形氧化铝，其在室温下稳定α-AlH 3颗粒。
The dehydriding reaction of α-AlH3 induced by high-energy electron irradiation was observed in situ by transmission electron microscopy and associated electron energy-loss spectroscopy (EELS). An α-AlH3 crystal decomposed into fine aluminum particles while retaining its initial external shape because of a thin rigid surface layer that covered the entire particle. EELS revealed that the thin surface layer was amorphous aluminum oxide, which stabilizes α-AlH3 particles at ambient temperature.
