“…Scanning electron microscopy (SEM) images show that CuO/Co 3 O 4 has a unique uniformly sized nanocube structure (Figure S3, Supporting Information). The typical X‐ray powder diffraction (XRD) pattern exhibits characteristic diffraction peaks corresponding to those of CuO (PDF#80‐1917) [ 28 ] and Co 3 O 4 (PDF#74‐2120), [ 29 ] presenting the coexistence of CuO and Co 3 O 4 phase ( Figure a). To determine the surface valence and chemical environment of the precursors and CuO/Co 3 O 4 , X‐ray photoelectron spectroscopy (XPS) was performed (Figure 1b,c, Figures S4 and S5, Supporting Information).…”

The electrochemical coupling of biomass oxidation and nitrogen conversion presents a potential strategy for high value‐added chemicals and nitrogen cycling. Herein, in this work, CuO/Co3O4 with heterogeneous interface is successfully constructed as a bifunctional catalyst for the electrooxidation of 5‐hydroxymethylfurfural to 2,5‐furandicarboxylic acid and the electroreduction of nitrate to ammonia (NH3). The open‐circuit potential spontaneous experiment shows that more 5‐hydroxymethylfurfural molecules are adsorbed in the Helmholtz layer of the CuO/Co3O4 composite, which certifies that the CuO/Co3O4 heterostructure is conducive to the kinetic adsorption of 5‐hydroxymethylfurfural. In situ electrochemical impedance spectroscopy further shows that CuO/Co3O4 has faster reaction kinetics and lower reaction potential in oxygen evolution reaction and 5‐hydroxymethylfurfural electrocatalytic oxidation. Moreover, CuO/Co3O4 also has a good reduction effect on . The ex‐situ Raman spectroscopy shows that under the reduction potential, the metal oxide is reduced, and the generated Cu2O can be used as a new active site for the reaction to promote the electrocatalytic conversion of to NH3 synthesis. This work provides valuable guidance for the synthesis of value‐added chemicals by 5‐hydroxymethylfurfural electrocatalytic oxidation coupled with while efficiently producing NH3.

Developing efficient electrooxidation 5‐hydroxymethylfurfural (HMF) catalysts with high selectivity and fast reaction kinetic is challenging. The HMF oxidation reaction (HMFOR) involves the adsorption of HMF and OH− on the catalyst, thus understanding the adsorption behavior between the catalyst surface and reactants is vital. In this work, by studying the relationship between HMFOR performance and the adsorption behavior of reactants on different transition metal oxides (TMOs), it is discovered that the catalytic performance of TMOs is related to the adsorption capacity of OH− and HMF simultaneously. Subsequently, TMOs with different HMF and OH− adsorption abilities are coupled to further optimize the catalytic performance of HMFOR. Experimental and theoretical calculation results indicate that the electronic interactions between different TMOs can regulate the substrate adsorption behavior and electron transfer ability of the catalysts, which is beneficial for HMFOR. Among them, due to the strong interaction between the three components optimizes the adsorption capacity for HMF and OH−, NiO/CuO/Co3O4 exhibits the best HMFOR performance with FDCA selectivity of 99.6% and formation rate of 16.45 mmol gcat−1 h−1. This work provides a design principle for HMFOR catalysts by modulating the adsorption behavior of reaction molecules.
