Well aligned Li-dispersed manganese oxide nanotubes were prepared using LiNO3, Mn(NO3)2 x xH2O and an anodic aluminum oxide template by solvent-free method for potential applications in H2 storage. The obtained nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The analyses revealed the Mn2O3 nanotubes to have a cubic structure with a uniform length, 40-50 nm in wall thickness and 250 +/- 10 nm in the outer diameter. The level of H2 adsorption was determined using the gravimetric method. The Li-dispersed manganese oxide nanotubes showed a 0.26 wt% for the amount of hydrogen adsorption at 77 K under 4.5 MPa.
采用硝酸锂、硝酸锰·x水合物和阳极氧化铝模板,通过无溶剂法制备了排列良好的锂分散氧化锰纳米管,用于潜在的储氢应用。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对所得纳米管进行了表征。分析表明,Mn2O3纳米管具有立方结构,长度均匀,壁厚40 - 50 nm,外径250±10 nm。采用重量法测定了氢气吸附量。锂分散氧化锰纳米管在4.5 MPa、77 K下的氢气吸附量为0.26 wt%。
