The limitations of current benchmark oxygen electrocatalysts, such as RuO 2 , IrO 2 , and Pt/C, due to their high cost, scarcity, and unifunctionality, have inspired a search for more effective oxygen catalysts to advance sustainable enegry solutions. Hence, development of cost-effective bifunctional catalysts to overcome the issues associated with benchmark catalysts is crucial. Metal−organic framework composites containing conductive carbon materials present promising solutions to these challenges. This study reports the synthesis, characterization, and application of a metal−organic framework of cobalt(II) tetra(3-hydroxy tyramine) phthalocyanine polymer, poly[Co (II) THTPc], for bifunctional oxygen electrocatalysis. The synthesis methodology is simple, cost-effective, and sustainable. To improve the catalytic performance of poly[Co (II) THTPc], an organic-hybrid composite was prepared by incorporating Ketjen black (KB) nanoparticles at an optimized ratio. The resulting poly[Co (II) THTPc]:KB (4:1, respectively) hybrid exhibited outstanding catalytic activity for OER bearing an overpotential of 359 mV on a Ni foam substrate and 371 mV on a glassy carbon electrode (GCE) substrate at 10 mA cm −2 current density in 1.0 M KOH at 5 mV s −1 scan rate. Furthermore, the same composite catalyst demonstrated an onset potential of 0.876 V vs RHE for ORR with a half-wave potential of 0.767 V vs RHE, obeying four-electrontransfer pathway in the same electrolyte and scan rate on GCE. In addition, the designed hybrid catalyst demonstrated improved catalytic properties compared to standard catalysts, including a lower Tafel slope, reduced charge-transfer resistance, and higher exchange current density for OER and ORR. The remarkable catalytic performance of the developed hybrid can be attributed to various synergistic effects, favorable π−π interactions, and increased number of electroactive sites that downshifts the D-band center of Co adsorption sites, effectively reducing the activation barrier of reaction intermediates in both the OER and ORR. Importantly, the low-cost bifunctional oxygen catalyst exhibited excellent stability and efficiency, making it a potential bifunctional oxygen electrocatalyst for large-scale integrated green energy systems.
