Invited for this month′s cover is the group of Jaeyoung Lee at the Gwangju Institute of Science and Technology (GIST). The cover image shows how the lone‐pair electrons on N atoms could play a role in both uniform nucleation of Pt nanoparticles and facile oxygen reduction reaction (ORR). Strong Pt−N interaction based on π‐backdonation improves not only the activity of the ORR but also the durability in the polymer exchange membrane fuel cells.
