摘　　要：以二种中国煤为原料,用射频等离子体法制备洋葱状富勒烯(Onion -likeFullerenes:OLFs) ,就压力对产物的影响进行了讨论。OLFs的表征采用高分辨透射电镜(HRTEM)和X射线衍射(XRD)等技术。结果表明:在其它工艺条件相同的情况下,压力为30Pa适合OLFs生长;实验所用煤均可大量制备OLFs,纯度较高,为OLFs的制备开拓了廉价生产的新途径。Onion-like fullerenes (OLFs) were synthesized by radio frequency plasma from two Chinese coals. Effects of pressure on the products were discussed. The morphologies and structures of the products were characterized by high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) techniques. Results reveal that OLFs are easier to grow under the pressure of 30 Pa. OLFs can be synthesized from the two Chinese coals with high purity and large quantities. The method described here might be used to synthesize pure OLFs at low costs.
