Abstract

Abstract : Durability of catalysts for the oxygen reduction reaction (ORR) should be guaranteed for long‐term operation of fuel cells. In article number1802228, Hu Young Jeong, Hyeon Suk Shin, Hyun‐Kon Song, and co‐workers design a catalyst/support system to confine platinum nanoparticles within holes of graphene for suppressing platinum agglomeration. Spherical multifaceted platinum particles are evolved to {110}‐dominant dendritic multipods within the nano‐dimensional space during repeated ORR processes.
