- Production of High‐Purity 2,5‐Furandicarboxylic Acid through Electrocatalytic Oxidation of 2,5‐Bis(hydroxymethyl)furan over Reconstructed Ni2P/NF Zelin Li Jingqing Tian Jiabiao Yan Bing Ma Lisong Chen Chen Zhao ChemSusChem The generation of high‐valence surface active species (such as CoOOH and NiOOH) determines the crucial oxidation rates and stabilities in the electrocatalytic reactions. Herein, a unique Ni2P/NF catalyst is designed using a chemical vapor deposition method along with a rapid reconstruction (Ni2+ → Ni3+) rate, stably achieving ≈90% FDCA yields from BHMF electron‐oxidation after 10 cycles at a formation rate of 218 μmolFDCA cm−2 h−1 (seven times higher than data in reported literature). The abundance of available electrons near the Ni‐3d Fermi level, together with the reduced NiP bond strength and the lowest electronegativity of Ni2P, accelerates surface NiOOH species formation. In addition, the electrocatalytic oxidation of BHMF offers a more stable furan‐based substrate, while also prolonging the residence time of the oxidative intermediate HMF. This mitigates humin formation, thereby enabling the synthesis of high‐purity FDCA (>99%) at high concentrations (100 mmol L−1), making it a promising approach for efficient FDCA synthesis. 10.1002/cssc.202500544 http://onlinelibrary.wiley.com/termsAndConditions#vor
