CuCoO2 anchored on g-CN as a highly efficient and durable electrocatalyst for OER performance

The excessive Utilization of fossil fuels is increasing energy shortage as well as several environmental issues. Sustainable and renewable energy systems are essential for the production of cost-effective electro-catalysts that exhibit long-term durability and superior electrocatalytic performance to improve oxygen evolution reaction (OER). Delafossite oxide was recently discovered as a viable alternative to the precious metal catalysts of RuO2 and IrO2. They can serve as highly efficient electrocatalysts in OER. This study used a low-cost, simple hydrothermal method to fabricate CuCoO2-supported g-CN, which was then characterized utilizing scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The CuCoO2/g-CN nanomaterials were analyzed in a 1.0 M KOH solution using several electrochemical methods. Additionally, the kinetic mechanisms of CuCoO2/g-CN composite electrocatalyst were examined using LSV, chronoamperometry, CV, and EIS to assess stability and performance of the catalytic mechanism. Electrochemical results show a significant overpotential of 197 mV at 10 mA cm−2 Cd and a Tafel value of 34 mV dec−1, lower Rct (2.74 Ω), and greater stability for 30 h. As a result, manufactured material performs exceptionally well in the OER procedure and in a variety of potential devices.
