摘要: Comparative investigation of the electrochemical oxygen evolution reaction (OER) activity for clean energy production was performed by fabricating three different electrodes, namely, NiSe2, CoSe2, and CoNiSe2, synthesized hydrothermal treatment. Cubic, orthorhombic, hexagonal structures CoNiSe2 were confirmed X-ray diffraction (XRD) also other characterization studies. Perfect nanospheres, combination distorted nanospheres tiny nanoparticles, sharp-edge nanostructures explored surface morphological images. Higher OER binary electrode achieved as 188 mA/g current density with a comparatively low overpotential 234 mV along higher conductivity charge transfer resistance when compared to its unary NiSe2 CoSe2 electrodes. A Tafel slope value 82 mV/dec same in half-cell configuration. The overall 100% retention all fabricated electrodes stability test suggested that excellent optimum condition obtained during synthesis. This could definitely be revelation synthesis novel combinations affordable metal selenides production.
