本文综述了近年来日本在碳孔隙结构控制方面的研究进展。特别强调了微孔和介孔的控制。介绍了为此目的所采用的方法的细节。微孔控制的主要目的是制备具有均匀微孔结构的分子筛碳（MSC）。这种间充质干细胞是用以下独特的技术制备的；金属阳离子交换树脂的炭化和苯在活性炭纤维上的热解积碳。此外，还将几种有机聚合物薄膜碳化合成了用于气体分离的高性能间充质膜。为了控制介孔，人们提出了许多新的方法，如催化活化、聚合物共混碳化、有机凝胶碳化和模板碳化。讨论了这些方法在未来工业应用中的可行性。(C) 2000 Elsevier Science Ltd.版权所有。
The present review describes the recent activities in Japan on the study of pore structure control in carbon. Special emphasis is put on the control of both micro- and mesoporosity. The details of the methods employed for this purpose are introduced. The main aim in the control of micropores is to produce molecular sieving carbon (MSC) with uniform micropore structure. Such MSCs are prepared with the following unique techniques; the carbonization of metal cation exchanged resin and pyrolytic carbon deposition from benzene over activated carbon fiber. Furthermore, high performance MSC membranes for gas separation are synthesized from the carbonization of several types of organic polymer films. For the control of mesopores, many novel methods are proposed such as catalytic activation, polymer blend carbonization, organic gel carbonization and template carbonization. The availability of these proposed methods is discussed in relation to future industrial application. (C) 2000 Elsevier Science Ltd. All rights reserved.
