沈阳航空航天大学毕业设计（论文） PAGE XXXVIII PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT I 摘 要 炭吸附材料由于具有较大的比表面积，稳定的物理、化学性质，具有较强的吸附性能，已成为最具代表性的一类空气净化材料。碳纳米管具有一些独特的性质，如特殊的导电性能、力学性质及物理化学性质等。因此碳纳米管自出现以来即引起关注并广泛应用于诸多科学领域。碳纳米管（CNTs）由于具有较大的比表面积，因此具有良好的吸附能力，现在已经被应用于储氢及吸附剂等领域。 本次研究主要是针对CNTs的吸附能力，通过KOH活化的方法进一步增大CNTs的比表面积，进行甲基橙吸附实验并探索活化需要的最佳碱炭比，之后通过改变其它因素如震荡时间及CNTs的用量进一步探究CNTs的吸附能力。 关键词：吸附材料；碳纳米管；活化； PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT I Abstract Carbon adsorption material has larger specific surface area, stable physical and chemical properties, with strong adsorption properties, has become a kind of the most representative materials of air purification. Carbon nanotubes have some unique properties, such as special conductive properties, mechanical properties and physical and chemical properties. Therefore carbon nanotubes since there has caused concern and that is widely used in many fields of science.As Carbon nanotubes (CNTs) has a larger surface area, it has a good adsorption capacity, has now been applied to the field of hydrogen storage and adsorbent. This study focuses on the adsorption capacity of CNTs. Using the KOH activation method increase the specific surface area of CNTs. For methyl orange adsorption experiments and explore the best alkali activated carbon ratio required. Then chang other factors such as the shock time and the amount of CNTs to further explore the adsorption capacity of CNTs.
