Abstract
A review with 41 refs.; d. functional theory enables quant. computational anal. of reaction intermediates. The cluster approach makes application to heterogeneous catalysis possible. Examples from transition metal catalysis and zeolite catalysis will be discussed. In the case of transition metals cluster choices will be analyzed to simulate properties of the extended surface. The issue of coverage dependent reactivity and surface reconstruction will be discussed. The concept of adatom basicity in metal catalysis will be analyzed. It will be shown that the information obtained on the elementary reaction steps from cluster can be used to predict the overall rate of a catalytic reaction. In transition metal catalysis for an oscillatory reaction as the CO oxidn. reaction catalyzed by (100) it will be shown how knowledge on the elementary reaction rate consts. of surface reactions can be used to predict the overall rate of the reaction with help of the time dependent Monte Carlo method. In zeolite catalysis the anal. of the reaction mechanism of methanol conversion will be used to show the strength of the cluster approxn. for the case of a refractory oxide. The hydroisomerization reaction will be used to relate microscopic mol. information to the overall rate of a zeolite catalyzed reaction
