Description
Summary:Au‐segregated intermetallic AuCu3/C nanoparticles with uniform dispersion and narrow size distribution around 3 nm are reported by D. Xia, J. Li, and colleagues on page 2662. These nanoparticles have excellent catalytic performance for ORR in alkaline solution, excellent durability, as well as methanol tolerance activities. The enhanced activities mainly result from the synergetic effects between electroactive Au and Cu atoms on the particle surface: Cu activates O2 adsorption, and Au promotes OH–desorption.
