如已报道的，以Y沸石为模板剂可以合成长程有序的高比表面积微孔炭。在这项工作中，我们尝试用其他几种类型的沸石(贝塔沸石、ZSM-5、丝光沸石和L沸石)合成多孔炭。特别注意了每种沸石的结构规律性是否可以转移到碳结构上，以及Y沸石的情况。然后考察了碳填充方法，以确定哪种方法给碳结构的规律性最高。结果表明，Y型沸石的最佳碳填充方式并不是其他沸石的最佳填充方式，碳的长程有序化的规律性程度强烈依赖于沸石的类型。生成的碳的规律性顺序为：β沸石；L沸石；丝光沸石；ZSM-5。从沸石孔道的大小和形状出发，讨论了沸石类型对规律性的影响。(C)2003爱思唯尔科学有限公司。保留所有权利。
As previously reported, high surface area microporous carbons with long-range order can be synthesized by using zeolite Y as a template. In this work, an attempt is made to synthesize porous carbon using several other types of zeolites (zeolite beta, ZSM-5, mordenite and zeolite L). Special attention is paid to whether the structural regularity of each zeolite can be transferred to the carbon structure as well as with the case of zeolite Y. The carbon filling method was then examined to see which gives the highest regularity to the carbon structure. It has been found that the optimum carbon filling method for zeolite Y is not an optimum one for the other zeolites and the degree of the regularity of long-range ordering in the carbons strongly depends on zeolite type. The order of the regularity in the resultant carbons is zeolite beta>>zeolite L>mordenite> ZSM-5. The effect of zeolite type on the regularity is discussed in relation to the size and the shape of the zeolite channels. (C) 2003 Elsevier Science Ltd. All rights reserved.
