Catalysis is at the heart of the chemical industry. Essentially all commodity chemicals, including fuels, are produced by transformation processes related to catalysis. More than a century, there have been ongoing quests for the design principle and synthetic method for highly active and durable catalysts for many different reactions. And these quests can be rooted to identify and optimize catalytic active centers, usually interface and surface sites. This talk will show some advanced catalysts we developed through tailoring interface and surface microenvironment in metal-support catalysis with a specific focus on Pt and Au nanoparticle based catalysts. The synthetic method, advanced characterization, catalysts' evaluation and theoretical prediction will be covered. CO oxidation, as a prototype reaction, will be discussed in detail to provide some fundamental understanding of the catalytic active center.
