Built-in electric field and hydrophilicity-enhanced heterojunction for biomass electrooxidation

Caption

Schematic illustration of a CeO2/β-Ni(OH)2 heterojunction electrode for biomass-derived 5-hydroxymethylfurfural (HMF) electrooxidation..The intimate heterointerface generates a built-in electric field that promotes directional charge transfer and accelerates the formation of active NiOOH species. Meanwhile, the introduction of CeO2 significantly enhances surface hydrophilicity and substrate affinity, facilitating electron-proton transfer and boosting the efficiency of HMF electrooxidation.
