| 摘 要： | 利用混合酸对催化裂解法制备的多壁碳纳米管进行纯化,然后先后用氨水和柠檬酸对纯化后的多壁碳纳米管进行修饰,最后利用共沉淀法和热处理制各了碳纳米管氧化铕复合材料,并使用红外光谱、X-衍射仪(XRD)、扫描电镜(SEM)研究了碳纳米管及氧化铕复合材料的结构和形貌.光谱结果表明:经过混合酸纯化后,碳纳米管表面拥有丰富的羟基和羧基等官能团,而且能够在纯化后的多壁碳纳米管表面引入氨基和柠檬酸分子.电子显微图像显示,在450℃下热处理,获得了多壁碳纳米管/氧化铕纳米线复合材料;在750℃下热处理,获得了多壁碳纳米管/纳米氧化铕复合材料. |
| 关 键 词： | 碳纳米管 氧化铕 复合材料 纳米线 |

| Abstract: | Multi-walled carbon nanotubes (MWCNTs) were purified by immersing them in a 3:1 mixture of concentrated H2SO4 and HNO3 and then were modified with ammonia and citric acid (CA),respectively. Then the MWCNTs/europium oxide composite was prepared by co-deposition and heat treatment. Finally,the MWCNTs/europium oxide composite was investigated by X-ray diffraction (XRD),electron microscopes and IR. The results show that there are many oxygenated functional groups on the surface of the MWNT after the treatment o... |
