  1. 1 lanthanide hydrides ( m = la, nd, sm, dy and yb ) can be prepared easily by the direct hydrogenation of lanthanide metals catalyzed by ticl4 in tetrahydrofunan ( thf ) under normal pressure. the rate of hydrogenation decreased with increasing atomic number of lanthanides. transmission electron micrographs showed that the resulted lanthanide hydrides were in the form of nanoparticles with an average primary particle size around 20 - 40 nm

    本論文首次提出一種在溫和條件下催合成納米尺寸的金屬的方法,介紹在常溫常壓下,、釹、釤、鏑、鐿五種金屬在四呋喃( thf )溶劑中,催劑作用下與氣直接合形成相應的納米尺寸的金屬
  2. Nano - alkali metal hydrides and lanthanide hydrides can be prepared easily by the direct hydrogenation catalyzed by ticl4 in tetrahydrofunan ( thf ) under normal pressure. lanthanide powder of nanometric size in a finely dispersed active form was generated by the thermal decomposition of organolanthanide in vacuum. 1
