- 中文摘要: Monte Carlo simulations of modified Eley-Rideal mechanisms (ER) possessing decay and enhanced sticking probability and a three-step catalytic reaction (TCR) over fractal surfaces were performed to examine the morphological effect on these surface reactions. Effects of decay and enhancing profiles on the reaction probability distribution(RPD) for the ER reaction and effects of varying probability of reaction steps and cluster sizes on the normalized selectivity distribution (NSD) for TCR were then analyzed with multifractal scaling techniques. For the ER mechanism, RPD tends to be uniform for rapid decay and relatively concentrated at greater enhancing rate. For TCR, increased cluster size is found to decrease the position sensitivity of NSD. A large ratio of dimerization to isomerization increases the position distinction among active sites when the adsorption probability equals to unity. At small p/sub 1/, i.e., adsorption probability<<1, the ratio of dimerization to isomerization causes no effect on the NSD.
