Key Points

  • To investigate the impact of cobalt modulation on the electronic environment of NiCoMnCuFe high-entropy alloys for efficient water splitting.
  • Designed a cobalt-modulated NiCoMnCuFe alloy anchored on reduced graphene oxide (NiCoMnCuFe/RGO)
  • Evaluated electrocatalytic performance through oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) measurements
  • Measured Tafel slopes to assess catalytic efficiency
  • Achieved low Tafel slopes of 38.1 mV·dec−1 for OER and 64.1 mV·dec−1 for HER
  • Demonstrated excellent performance indicating high efficiency for overall water splitting
  • Revealed that cobalt modulation significantly enhances the local electronic environment

Abstract

A cobalt-modulated NiCoMnCuFe high-entropy alloy anchored on reduced graphene oxide (NiCoMnCuFe/RGO) was rationally designed, demonstrating excellent OER/HER performance with low Tafel slopes of 38.1 and 64.1 mV·dec−1, respectively. For overall...
