During this year (2016),I have done the experiment on the desorption properties of lithium alanate (LiAlH4) doped with lithium metatitanate (Li2TiO3). Transmission electron microscopy (TEM) observations help understand the catalytic effect of Li2TiO3 in the nanoscale. I have set the equipment of AC-impedance for investigated the lithium ionic conductivity of different samples, such as LiAlH4/ Li2TiO3, LiBH4/ Li2TiO3, LiNH2/ Li2TiO3, and LiH/Li2TiO3.I have investigated geikielite (MgTiO3) as catalyst in the complex hydrides, which shows good catalytic effect in LiAlH4 and MgH2.I have already published two papers in international journal. Another one manuscript has already been prepared and will submit soon.

在这一年（2016年），我做了掺杂偏钛酸锂（Li2TiO3）的丙酸锂（LiAlH4）解吸性能的实验。透射电子显微镜（TEM）的观察有助于理解Li2TiO3在纳米尺度上的催化作用。我设置了交流阻抗设备，对LiAlH4/ Li2TiO3、LiBH4/ Li2TiO3、LiNH2/ Li2TiO3、LiH/Li2TiO3等不同样品的锂离子电导率进行了研究。我研究了geikielite （MgTiO3）作为络合氢化物的催化剂，在LiAlH4和MgH2中表现出良好的催化效果。我已经在国际期刊上发表了两篇论文。另一份稿件已经准备好，将很快提交。
