Notes:
A model, which utilizes a Monte Carlo simulation, of the sintering and the redispersion of supported metal catalysts is presented and compared with experimental data from a Pt/Al2O3 system. The model is based on an atomic migration mechanism, but includes instantaneous diffusion and coalescence of crystallites of size 〈1 nm in reducing and inert atmospheres. It was found that behavior in reducing, oxidizing and inert atmospheres could be predicted.
