Iron (II) phthalocyanine covalently functionalized graphene as a highly efficient non-precious-metal catalyst for the oxygen reduction reaction in alkaline media Original Research Article Electrochimica Acta, Available online 8 September 2013, Pages Ying Liu, Li-Li Cui, Yan-Ying Wu, Guo-Jun Lv, Tao Pu, Xing-Quan He
Graphical abstractThe fabricated FePc-Gr catalyst for ORR exhibited high activity, favoring a direct 4-electron process, good stability and selectivity, all of which should be attributed to its high conductivity, the synergistic effect between FePc and graphene, as well as the formation of stable FePc-Gr composite through covalent bonding and π-π interaction.
