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 electrocatalytic activity to commercial C/Pt catalysts, but much better methanol tolerance and long-term stability toward ORR.
