Such a viewpoint of the effects of a little water addition has never been reported, it opened a new way to product SWCNTs with high purity and low cost. On the ground of the experimental results and mechanism studies, a little water addition may open a way for using the natural gas as carbon source to manufacture SWCNTs. By analyzing XRD, XPS results and with comparative experiments, we concluded that the active phases of SWCNTs growth in Ar were small Fe particles. A little W species can improve the surface characters of support and increase the dispersion of Fe particles, but higher W loading will cause large quantity of WC, which decompose CH〓 to amorphous carbon.

本文根据W-Fe-MgO催化剂中间产物和粗产物的XRD、XPS测量结果,结合制备实验和对比实验指出:在Ar中1073K下,生长SWCNTs的活性相是Fe的小颗粒,少量W在催化剂中以氧化物形式对载体表面改性,起提高Fe分散度的作用,但W浓度过高时在反应过程中会生成大量WC,又会催化CH〓分解为无定形碳,造成产物中SWCNTs含量下降。

Through the quantitative analysis of hydration water content and bound water content- in cement hydration resultants with mechanical properties, the results show crystallized hydration resultants attribute to strength continuly, while when the content of gel like hydration resultants is small, the attribute is low, when the content increase to a certain value, the action of gel like hydration resultants exceed crystallized hydration resultants.
