摘　　要：评述了纳米碳管（ＣＮＴ）的纳米孔隙结构及其决定的特殊物化性质，以及潜在的应用． ＣＮＴ孔径体系由多层次的孔隙组合而成，开口的一维中空管腔是最基本的孔隙结构，其纳米级的尺度和物理形态决定了它的超常吸附性质和其它物化特性，使ＣＮＴ成为极具潜力的纳米级能量载体；提供了进行一维物理化学过程的极限反应空间，是真正意义上的纳米反应器；ＣＮＴ的比表面积和孔径结构及其决定的吸附性质还决定或者影响着许多其它物化性质（如电磁性质）．发展纳米碳管中的物理化学研究，制备基于大表面积、可控孔结构ＣＮＴ的纳米器件，是ＣＮＴ领域的重要研究方向．The latest research advances on nano-sized porous texture of carbon nanotubes (CNTs), related properties and potential applications were reviewed. CNTs contain multi-types pores: opened one-dimensional inner hollow cavities, interstices between nanotubes in CNT arrays, and aggregated pores among arrays or isolated CNTs of large diameter. The first type of pore is elementary and the most important, and its very thin diameter (nanometer) and special configuration (cylindrical shape) may contribute to the uncommon adsorption properties (especially for hydrogen) and other properties, making CNTs potential nano-sized energy storage carriers. Furthermore, CNTs may act as the thinnest test-tube initiating the nano-sized chemical reaction and physical process. Since it is proved that specific surface area (SBET) and pore structure of CNTs determine the adsorption behaviors and other related physical and chemical properties, the study on chemistry in CNTs and development of nano-sized functional device based on CNTs of high SBET and controlled pore structures are important for the theoretical progress and application development of CNTs.
