摘要
概述了分形理论在多相催化剂表面几何结构特征研究中的应用 ,对多相催化剂表面的分形特征、分维数的类型以及在催化反应研究中广泛应用的三种分维数DC,DS 和DI 的测定方法进行了总结 。
The fractal features of the surface of the heterogeneous catalysis have been interpreted systematically.The methods of determination of three fractal dimensions(i.e. D C,D S,D I )as the quantitative expression to the irregularity surface are introduced for the main attention in this paper.A simple summarizes and reviews are given to the basic approach for studying heterogeneous catalytic reaction by means of fractal.
