Abstract Electrochemical oxidation of 5‐hydroxymethylfurfural (HMFOR) to generate high‐value chemicals under mild conditions acts as an energy‐saving and sustainable strategy. However, it is still challenging develop electrocatalysts with high efficiency good durability. Here, nickel foam (NF) supported CoCrCe(7.5%)‐LDH (layered double hydroxides) by doping Ce into CoCr‐LDH show (HMF) conversion (99%), 2,5‐furandicarboxylic acid (FDCA) yield Faraday (100%) at 1.4 V RHE . The also exhibits remarkable stability 97% HMF after 10 cycles. X‐ray absorption near‐edge spectroscopy (XANES) theoretical calculation that beneficial the formation high‐valance Co significantly facilitates electron transfer, regulates adsorption behavior intermediates, reduces Gibbs free energy barrier accelerates reaction rate. This work promotes use rare earth elements promote HMF.

Reconstruction-engineered electrocatalysts with enriched high active Ni species for urea oxidation reaction (UOR) have recently become promising candidates energy conversion. However, to inhibit the over-oxidation of brought by valence state Ni, tremendous efforts are devoted obtaining low-value products nitrogen gas avoid toxic nitrite formation, undesirably causing inefficient utilization cycle. Herein, we proposed a mediation engineering strategy significantly boost high-value formation help close loop employment economy. Specifically, platinum-loaded nickel phosphides (Pt-Ni
