Surface and interface dynamics

与固体表面接触的气体会改变它们，导致它们钝化，例如氢与硅接触，或腐蚀它们，例如氧或硫与金属接触。固体表面也可以作为化学反应的催化剂，例如铂合金可以将一氧化碳氧化为二氧化碳，某些铁矿石可以将大气中的氮转化为氨肥料（Haber-Bosch催化剂）。我们的吸附、脱附和表面反应理论研究了这些过程的微观基础，以帮助开发新的催化剂并进一步优化现有的催化剂。

Gases in contact with the surfaces of a solid will modify them leading to their pasivation, such as hydrogen in contact with silicon, or corrode them, such as oxygen or sulfur in contact with metals. Solid surfaces can also act as catalysts for chemical reactions, e.g. platinum alloys can oxidize carbon monoxide to carbon dioxide and certain iron ores can turn atmospheric nitrogen into ammonia fertilizers (Haber-Bosch catalysts). Our theory of adsorption, desorption and surface reactions examines the microscopic basis underlying such processes in order to help develop new catalysts and further optimize existing ones.
