Dendritic Multipods: Sphere‐to‐Multipod Transmorphic Change of Nanoconfined Pt Electrocatalyst during Oxygen Reduction Reaction (Small 2/2019)

Durability of catalysts for the oxygen reduction reaction (ORR) should be guaranteed for long-term operation of fuel cells. In article number 1802228, 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.
