Molecular Architecture of Cobalt Porphyrin Multilayers on Reduced Graphene Oxide Sheets for High-Performance Oxygen Reduction Reaction

ORR inspiring: Multilayers of Co2+ and porphyrin, fabricated on the surface of reduced graphene oxide sheets (see picture) by a layer‐by‐layer assembly technique, are potentially cost‐effective and high‐efficient oxygen reduction reaction (ORR) catalysts. The multilayers have comparable electrocatal...

Summary:ORR inspiring: Multilayers of Co2+ and porphyrin, fabricated on the surface of reduced graphene oxide sheets (see picture) by a layer‐by‐layer assembly technique, are potentially cost‐effective and high‐efficient oxygen reduction reaction (ORR) catalysts. The multilayers have comparable electrocatalytic activity to commercial C/Pt catalysts, but much better methanol tolerance and long‐term stability toward ORR.
