A novel three‐phase composite of Co/CoO/Co 3 O 4 is synthesized through straightforward calcination treatment towards cobalt‐based metal‐organic gel (Co MOG) precursor, which is constructed with the metal source of cobalt chloride and organic ligand of 4, 4', 4”‐((1, 3, 5‐triazine‐2, 4, 6‐triyl) tris (azanediyl)) tribenzoic acid at room temperature. The morphology, structure and composition of the derived Co/CoO/Co 3 O 4 is confirmed through scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X‐ray diffraction (XRD) and X‐ray photoelectron spectrums (XPS). Furthermore, the composite of Co/CoO/Co 3 O 4 is employed as electrode modified material with the excellent electrochemical performances of accelerating the electron transfer and boosting the electrode interface reaction. As a proof of concept, the electrochemical redox behaviors of diethylstilbestrol (DES) have been systemically investigated at the modified electrode interface and the established analytical approach for DES with the broad linear range and satisfied recovery. This work not only provided a facile approach to obtain electrode material with excellent electrochemical performance but also enriched the application of MOG materials in the electrochemical field.
