In this work,nickel foam supported CeO2-modified CoBDC(BDC stands for terephthalic acid linker)metal-organic frameworks(NF/CoBDC@CeO2)are prepared by hydrothermal and subsequent impregna-tion methods,which can be further transformed to NF/CoOOH@CeO2 by reconstruction during the elec-trocatalytic test.The obtained NF/CoOOH@CeO2 exhibits excellent performance in electrocatalytic oxidation of 5-hydroxymethylfurfural(HMF)because the introduction of CeO2 can optimize the elec-tronic structure of the heterointerface and accelerate the accumulation of*OH.It requires only a potential of 1.290 VRHE to provide a current density of 50 mA cm-2 in 1.0 M KOH+50 mM HMF,which is 222 mV lower than that required in 1.0 M KOH(1.512 VRHE).In addition,density-functional theory calculation results demonstrate that CeO2 biases the electrons to the CoOOH side at the heterointerface and pro-motes the adsorption of*OH and*HMF on the catalyst surface,which lower the reaction energy barrier and facilitate the electrocatalytic oxidation process.
