摘要：
A study was carried out on the oxidation of CO on catalysts with different fractal dimension in kinetic and internal diffusion modes. A linear relationship was found between the fractal dimension of the catalyst DF and the γ coefficient in the reaction-diffusion equation. The fractal dimension of the catalyst could be calculated from the macrokinetic measurements. © 2006 Springer Science+Business Media, Inc.
