摘要: Abstract This study investigates the performances of cobalt-based polyaniline hybrid electrocatalyst towards oxygen evolution reaction. The materials were prepared electrochemically using different deposition protocols. proved to have low overpotential, high current density, electrochemical surface area, and enhanced performance. Current-time chronoamperometric response was used stability electrode toward evolution. Scanning electron microscopy shows that protocols associated with significant changes in materials' morphology. Energy-dispersive X-ray spectroscopy verifies incorporation metal ions illustrates significantly alter film composition. diffraction patterns indicate preservation crystal structure Co3O4 after on ITO Pan.
