For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.

我们首次成功地用络合催化等方法取代需在高温高压下进行的传统方法，在温和条件下高效率地合成出纳米尺寸镧、钕、钐、镝、镱的金属氢化物；首次在常压常温的条件下，通过催化、引发等方法合成镧系金属有机化合物，再将其真空热分解成功地制备了纳米尺寸的镧、钕、钐、镝、镱等金属粉末；与传统方法不同，这些方法得到的产品基本颗粒尺寸小于 40 nm，遇到空气燃烧，具有极高的化学反应活性，使原来活性很低甚至观察不到活性的反应大幅度提高反应速率和产率；考察了制备方法、制备条件等因素对晶粒尺寸、比表面积大小等的影响规律。

After graduation, he continued to work at the same institute, engaged in the research of shock wave propagation in solids, hyper-velocity impact and shock wave consolidation.
