dc.description.abstract | A remaining challenge for deployment of proton-exchange membrane fuel cells is thelimited durability of Pt-nanoscale materials that operate at high voltages during thecathodic oxygen reduction reaction. In this work, atomic-scale insight into well-definedsingle crystalline, thin-film, and nanoscale surfaces exposed Pt dissolution trends thatgoverned the design and synthesis of durable materials. A newly defined metric, intrinsicdissolution, is essential to understanding the correlation between the measured Pt loss,surface structure, size and ratio of Pt-nanoparticles in carbon support. It was found that utilization of Au underlayer promotes ordering of Pt surface atoms towards (111)- structure, while Au on the surface selectively protects low-coordinated Pt sites. Thismitigation strategy was applied towards 3 nm Pt3Au/C nanoparticles, resulting inelimination of Pt dissolution in liquid electrolyte, including 30-fold durability improvementvs. 3 nm Pt/C over extended potential range up to 1.2 V. | en |
