石墨化碳空心球因具有密度小、稳定性好和可填充中空结构等特点,受到了研究者的广泛关注。本文结合国内外的研究进展,综述了近年来发展起来的采用过渡金属如铁、钴、镍等为催化剂,低温(〈1000℃)催化法合成石墨化碳空心球的最新研究进展。介绍了低温催化法提高碳空心球石墨化程度的机理,说明了石墨化碳空心球的表征方法,展望了石墨化碳空心球的应用前景。最后指出了相关研究中有待解决的问题。
Graphitized carbon hollow spheres exhibit excellent properties such as low density, good thermal and chemical stability and available hollow interior, which lead to extensive attention. In this review, we summarize the latest development of synthesizing graphitized carbon hollow spheres by low-temperature ( 〈 1 000℃) catalytic method with catalysts, such as Fe, Co, Ni and so on. The mechanism of low-temperature catalytic approaches is introduced. The characterizing methods of graphitized carbon hollow spheres and their applications are presented. Additionally, the challenges of the synthesis of graphitized carbon hollow spheres are discussed, and the problems still should be resolved are pointed out.
