The contribution made by surface science to understanding reactivity in heterogeneous catalysis

Abstract

The impact that surface science studies have made on understanding mechanism in heterogeneous catalysis is examined. An important function is to provide a data base on surface reactivity and a number of illustrative examples are presented. Studies of the catalytic reactivity of single crystals are particularly important and cases discussed include the synthesis of both ammonia and methanol, and the reactions important in automotive exhaust purification. The role of theoretical studies in explaining promotion and poisoning of catalysts is discussed and lastly some future trends in both surface science and catalysis research are identified.
