碳納米管具有典型的層狀中空結(jié)構(gòu)特征,由六邊形碳環(huán)微結(jié)構(gòu)單元組成,是一種具有特殊結(jié)構(gòu)的一維量子材料。它主要由呈六邊形排列的碳原子構(gòu)成數(shù)層到數(shù)十層的同軸圓管。由于其獨(dú)特的結(jié)構(gòu)，碳納米管的研究具有重大的理論意義和潛在的應(yīng)用價值，如它有望用作為分子導(dǎo)線，納米半導(dǎo)體材料，催化劑載體，分子吸收劑和近場發(fā)射材料等, 有望廣泛地應(yīng)用于諸多領(lǐng)域.
近幾年來研究表明碳納米管具有很好的催化特性，可以用作催化劑，替代金屬氧化物，甚至貴重金屬。 例如，碳納米管可用于烷烴脫氫反應(yīng)的催化劑，不僅顯著提高了丙烯、丁烯、丁二烯、苯乙烯等烯烴的選擇性，而且可以將工業(yè)路線的反應(yīng)溫度降低約200～300攝氏度，乙苯等烷烴氧化脫氫選擇性高于90%，且烷烴脫氫反應(yīng)溫度比現(xiàn)有工業(yè)化過程低200- 300度。

1.The multi-wall carbon nanotubes(MWNTS)are produced by a catalytic vapor deposition process.
2.The main industial usage of MWNTs is an additive in polymers、rubbers、merals、and others by leveraging its high electrical and themal conductivity,superior mechanical property and very high aspect ratio. The current applicationgs of MWNTs include conductive plastics, Li-ion batteries,sports goods,and so on.
