Replacing energy-intensive thermal synthesis, we report a green electrocatalytic strategy for phenol hydroxylation to hydroquinone (HQ) using a novel Ni-V bimetallic phosphide (P- NiV) catalyst. Synthesized via phosphating NiV-LDH, P-NiV exhibits enhanced conductivity, stability, and active site regulation, confirmed by SEM/XRD. Under optimal conditions (0.5 V vs RHE, 40°C), P-NiV achieved 57.7% phenol conversion and 62% HQ selectivity. This electrocatalytic approach significantly lowers energy consumption and operating temperature compared to thermal methods, offering a sustainable alternative for industrial HQ production.
