【摘要】 大部分催化剂结构复杂,准确地描述其繁杂的构型、从分子水平上了解催化剂的性能是极其重要的工作。传统的研究方法对此无能为力,而分形的引入为研究催化剂提供了一条新思路。论述了可用于多相催化中分维数的测定方法,回顾了国内分形用于催化研究的情况,并对分形在多相催化中的发展进行了展望。更多还原

【Abstract】 Most catalysts have complex structures. It is important to precisely depict their intricate configuration and investigate effect of the structure from molecule level. The advent of fractal provides a new way for investigating structures of catalysts. The means for determining fractal dimensions of the surface of heterogeneous catalyst were described. Application of fractal in catalysis researches in China were reviewed. The prospect of fractal in heterogeneous catalysis researches was outlined, too.更多还原
