Bifunctional multi-metallic nitrogen-doped nanocarbon catalysts derived from 5-methylresorcinol
High-performance bi- and trimetallic nitrogen-doped nanocarbon catalysts for the electrochemical oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) were prepared by high-temperature pyrolysis from 5-methylresorcinol, dicyandiamide and transition metal (Ni, Fe and/or Co) salts.

| description | High-performance bi- and trimetallic nitrogen-doped nanocarbon catalysts for the electrochemical oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) were prepared by high-temperature pyrolysis from 5-methylresorcinol, dicyandiamide and transition metal (Ni, Fe and/or Co) salts. The electrocatalytic activity of the catalysts was studied using the rotating disc electrode (RDE) method in alkaline solution. The trimetallic NiFeCoNC electrocatalyst showed the best bifunctional ORR/OER performance with the ΔE value of 0.75 V. This is attributed to the synergistic effects between transition metals in the active sites of the material and a hierarchically porous microstructure, achieved through the reactive carbonitride template formed from dicyandiamide during the pyrolysis. |
