摘要：
The surface of a catalyst is a fractal, and its fractal dimension can strongly influence the performance of a catalytic reaction. By means of the Monte Carlo method, the decompositions of N2O on a square lattice and a fractal surface are investigated in this paper. From the simulation it is found that the fractal surface can change both the reaction rate constant K and the reaction order alpha in the N2O decomposition, and all of these changes are caused by the abnormal diffusion of the surface species on the fractal surface.
