The importance of catalysis is undoubtedly growing but our understanding of catalytic reactions at a molecular level is not keeping pace. A step change in performance may require a radical new strategy that enables a 'smart design' approach where every element of catalyst structure is deliberately constructed. To achieve this ambitious goal we must first identify the nature of sites responsible for catalytic activity and develop an understanding of how a catalyst operates at an atomic level.This project will provide a fundamental understanding of thenature of active sites through the study of model systems using modern ultra-highvacuum (UHV) surface science methods capable of exquisite sensitivity.

催化的重要性无疑在不断增长，但我们对分子水平上的催化反应的理解却没有跟上。性能的阶跃变化可能需要一个激进的新策略，该策略能够实现“智能设计”方法，其中催化剂结构的每个元素都是故意构建的。为了实现这一宏伟目标，我们必须首先确定负责催化活性的位点的性质，并在原子水平上了解催化剂如何运作。该项目将通过使用现代超高真空（UHV）表面科学方法研究模型系统，提供对活性位点性质的基本了解。
