Outline of Final Research Achievements

In this project, we propose new synthetic way for reducing the use of Pt in a catalytic system by increasing the surface area and modifying the Pt surface structure (i.e., alloying). Several types of mesoporous Pt films with different pore sizes ranging from 5 to 50 nm are prepared by electrochemical plating in aqueous surfactant solutions. Interestingly, the atomic crystallinity in the pore walls is coherently extending across over several mesopores, showing a large number of atomic steps. These can serve as active sites for electrochemical reactions. As a result, our mesoporous Pt and Pt-based alloys exhibit high potentiality as a superior electrocatalyst.
