Electrocatalytic Activity of Reduced Graphene Oxide Supported Cobalt Cinnamate for Oxygen Evolution Reaction

The stability of porous coordination polymers during an electrochemical reaction could be improved by introducing supporter materials. An I3O0-type inorganic hybrid electrocatalyst, cobalt cinnamate, supported on reduced graphene oxide (rGO) was successfully prepared for oxygen evolution reaction. electrocatalytic activity and cinnamate(catalyst)/rGO composite were significantly due to the strong interaction between catalyst supporter, which led enhanced anchoring electrical conductivity. catalyst/rGO shows ~30 mV reduction in overpotential improvement durability from ≥35% ≥70% after a time 12 h, compared alone.
