| Abstract Scope |
Two families of Dugganite were synthesized through the solid-state method and both samples provided a three-dimensional framework structure. These samples were investigated for the evolution of color by doping transition metal ions in place of Zinc ions. The doped Dugganite was characterized by optical absorption spectral studies and color coordinates were determined from the CIE 1931 chromaticity diagram. The cobalt-substituted dugganite was investigated for the oxygen evolution reaction which showed superior electrocatalytic OER activity in the alkaline medium with a low overpotential value, lesser tafel slope value, and excellent stability. We have explored a new way for the structural design of cobalt-substituted dugganite to apply electrocatalytic water splitting. We probe the electroactivity of the oxide material based on linear scan voltammetry to find on-set potential, impedance for finding charge transfer resistance, chronoamperometry to know the stability of the electroactive material, and electrochemical surface area for finding the catalyst activity. |
