Transition metals including noble ones possess wide applications in heterogeneous catalysis. Their surface local structures and properties virtually dictate their catalytic activity and selectivity, which is the main research focus in surface and catalysis. On metal single crystals and films, controlled preparations of surface structures play an important role in exploring the relationship between surface properties and surface probe reactions, and lay a solid foundation in achieving precise control of surface reactions. This project is making use of the ultrahigh spatial and energy resolutions of low temperature scanning probe microscopy to study the geometric and electronic properties of the substrate surfaces and adsorbed molecules, aiming at searching for the efficient ways to tune the surface activities of metals and surface molecular reactions at the atomic and molecular levels. The implementation of this project will be beneficial for our deep understanding of surface reactions and establish the scientific basis for the development of high-performance catalysis.
