Ensemble effects of high entropy alloy for boosting alkaline water splitting coupled with urea oxidation

FeCoNiMoRu/CNFs exhibits a small potential of 1.43 V vs. RHE (100 mA cm −2 ) and superior stability for 90 h toward urea electro-oxidation (UOR). In situ electrochemical Raman results strongly demonstrate the ensemble effects of the various metal sites on improving the UOR activity by co-stabilizing...

Description
Summary:FeCoNiMoRu/CNFs exhibits a small potential of 1.43 V vs. RHE (100 mA cm −2 ) and superior stability for 90 h toward urea electro-oxidation (UOR). In situ electrochemical Raman results strongly demonstrate the ensemble effects of the various metal sites on improving the UOR activity by co-stabilizing the important intermediates. This work will open new directions in the application of high-entropy alloys for small molecule oxidation reactions. Due to the ensemble effects of various metal sites in co-stabilizing the important intermediates, FeCoNiMoRu/CNFs exhibits a small potential of 1.43 V vs. RHE (100 mA cm −2 ) and superior stability for 90 h toward the UOR.
