摘　　要：研究了不同的碳纳米管预处理方法对制备碳纳米管负载氧化铁催化剂的影响。通过透射电镜观察了氧化铁负载前后碳纳米管表面的形貌,X射线衍射分析显示碳纳米管上包覆的是αFe2O3,并利用红外光谱和热重分析结果探讨了氧化铁负载的机理,发现经过预处理的碳纳米管吸附Fe(NO3)3后高温热处理得到的氧化铁是由Fe(NO3)3直接分解得到的。In this paper, the influences of different pre-treated carbon nanotubes on the preparation of carbon nanotube loaded by ferric oxide have been investigated. The images of composite catalysts were observed through TEM, the analyses of XRD showed that ferric oxide wrapping on carbon nanotubes was α-Fe2O3 and the mechanism of carbon nanotube loaded by ferric oxide was discussed by utilizing IR and TGA. Pre-treated carbon nanotubes absorbed by Fe（ NO3 ）3 were annealed , and then the composite catalysts of carbon nanotube loaded by ferric oxide was directly gained.
