The development of highly sensitive electrocatalysts for the electrochemical detection of ortho-nitrophenol (ONP) is critical for environmental monitoring due to its high toxicity in water environment. Herein, a novel electronic configuration engineering on CoSeO₃/AlO(OH) heterostructure with precisely modulated d-band centers is successfully designed. Crucially, a negative shift in the d-band center enhances the catalysis and adsorption ability of the heterostructure. Benefiting from the electron transfer behavior from AlO(OH) to CoSeO₃, the electrocatalyst exhibits exceptional ONP sensing performance, achieving an ultrahigh sensitivity of 0.499 μA L μmol^-1 and a record-low detection limit of 5.353 nmol/L. Furthermore, the experimental characterizations and density functional theory (DFT) calculations reveal that the heterostructure-induced d-band center downshifting optimizes the adsorption strength of ONP, further accelerating the electrochemical redox kinetics. The CoSeO₃/AlO(OH) also demonstrates good stability, anti-interference capabilities, and successful application in detecting ONP in real water samples. This study offers a promising strategy for designing advanced electrochemical sensors through heterointerface-based electronic structure engineering.
