Abstract

We have recently started efforts to develop a "catalyst by design" protocol that iteratively employs theoretical modeling and experimental results to systematically design a catalyst. In this approach, a variety of catalysts are first examined by theory and the most promising candidates are then synthesized experimentally, characterized, and tested. In our presentation, we report on our "catalyst by design" efforts employing supported platinum clusters. We will describe the nanostructure of Pt clusters and its interactions with CO and NO and compare it with theoretical studies. We will also summarize nanostructural changes in Pt clusters under CO and NO oxidation conditions. Our experiments on model catalysts validate theoretical studies and suggest that "catalyst by design" protocol can be highly effective in catalyst design provided it can be validated for a complex catalyst system such as emission treatment catalyst.
