Abstract

Here, we report that a Bi-doped Co₃O₄ nanosheet array grown on Ni foam can selectively catalyze HMF-to-FDCA oxidation at ambient conditions. The catalyst shows a faradaic efficiency of 97.7%, a yield rate of 362.5 μmol h⁻¹, and a conversion of nearly 100%, surpassing those of pristine Co₃O₄. Furthermore, when the catalyst was adopted as both the anode and cathode in a two-electrode system, H₂ and FDCA can be produced simultaneously.
