摘要
Supported mixed metal oxide systems, Cu-Cr on gamma-Al2O3, and gamma-Al2O3 + SiO2 were prepared and studied using fractal theory. The catalysts exhibit fractal properties. Fractal dimensions were computed analyzing the SEM images using the correlation function method and the variable length scale method. The influences of the support and of the preparation procedures on fractal properties are emphasized.
