Facile Synthesis of Porous ZnCo₂O₄ Nanorod for Efficient Electrochemical Degradation of Methylene Blue

This study employs a simple and feasible approach for fabricating the porous ZnCo2O4 catalyst with excellent electrochemical activity. We offer insight into the excellent performance of these catalysts by coupling electrochemical measurements with physical characterization methods. These embrace electron microscopy to investigate the morphological structure of the porous catalysts, cyclic voltammetry (CV) to determine the electrochemically active surface area of catalyst materials, linear sweep voltammetry (LSV) to evaluate the oxygen evolution potential (OEP), and electrochemical degradation experiment to assess the degradation performance. ZnCo2O4 porous catalyst exhibits durable stability and high OEP, and provides a large active surface and sufficient numbers of active sites for electrochemical reactions. The ZnCo2O4 porous catalyst can be anticipated as a highly active electrode material for wastewater treatment. This study provides a viable strategy for developing highly active and stable electrode materials on electrochemical applications. [GRAPHICS] .
