络合催化 meaning in English
coordination catalysis
Examples
- 3 . the reaction of lanthanide powder with anthracene in the presence of ticl4 catalyst in tetrahydrofuran at 0 - 60 under normal pressure generated organolanthanide compounds , which are less thermal . it was found that the decomposition of the organolanthanide compounds in vacuum could give rise to lanthanide powder of nanometric size with high purity accordingly
3 .纳米尺寸镧系金属粉末制备的研究温和条件下，采用络合催化法合成镧系金属有机化合物，利用它的热不稳定性，在真空条件下进行热分解来制备纳米尺寸镧系金属粉末。 - 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
