Tóm tắt

 The main goal of this project is to gain fundamental knowledge about the relation between surface composition and catalytic performance of Pt alloy catalysts for oxygen reduction reaction (ORR). Specific objectives are: to develop and improve a first-principles based multiscale computation approach to simulating surface segregation phenomena in Pt alloy surfaces
  to evaluate the surface electronic structure and catalytic activity of Pt alloy catalysts and
  to relate the surface composition to the catalytic performance of Pt alloy catalysts.
