Implication

Experimental exploration reveals dopant effects on oxygen evolution reaction in CuCo2O4, indicating improved performance.

Key Points

  • Dopants significantly enhance oxygen evolution reaction performance, with Ni yielding the lowest overpotential of 350 mV at 50 mA cm−2.
  • Electrochemical evaluations utilized techniques like cyclic voltammetry and electrochemical impedance spectroscopy to assess dopant impacts.
  • X-ray diffraction confirmed successful incorporation of dopants while preserving the cubic spinel structure.
  • Strategically doped CuCo2O4 demonstrates promise as efficient electrocatalysts, highlighting the relation between dopant choice and electrochemical performance.
