• A novel high-performance bi-functional electrocatalyst was fabricated by in situ growth of ZIF-67 polyhedrons onto Ba_0.5Sr_0.5Co_0.8Fe_0.2O₃ (BSCF) particles.

• Strong coupling between different phases endowed the robust structure to the composite, which translated into stable charging/discharging operation for 300 h. And the new interfacial phases significantly promoted the catalytic activity, stability and electrical conductivity.
