Abstract: Cyano-bridging metal organic frameworks or Prussian blue analogues (PBA) have attracted much attention for developing electrochemical-based devices because of large surface area, stability, conductivity and interesting redox features. Herein, nickel-iron cyano-bridging metal framework (NICF) was prepared by a simple co-precipitation method, calcined at high temperatures and the utilized for electrochemical applications. Nano-sized nickel-iron cyano-bridging metal framework with a large surface-area and pure cubic crystal was obtained. The NICF was calcined at different temperatures (100, 200, 300, 400 and 500 ^oC) then the electrochemical properties were studied by simple drop cast on a glassy carbon electrode (GCE). Interestingly, the S100/GCE platform (for NICF sample calcined at 100 ^oC) showed a superior specific capacitance (C_s) of 571 F/g compared to 428 F/g for NICF/GCE in 0.1M KOH. While, the S200/GCE (for NICF calcined at 200 ^oC) exhibited a low overpotential (η) of 450 mV toward oxygen evolution reaction (OER) compared to 1.0 V and 1.3 V for as-prepared NICF modified GCE and unmodified GCE, respectively to deliver a current density of 10 mA/cm² in 1.0 M KOH. Based on these results, it was found the thermal curing of NICF at relatively high temperature could be used as a simple approach for boosting the electrochemical features of PBA leading to design efficient and low-cost electrochemical-based devices.
