A novel sensing material of cobalt oxide-bismuth phosphate (Co3O4–BiPO4) was prepared by the hydrothermal method. Thus prepared sensing material was characterized by X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM). The sensor was used for the determination of epinephrine by using modified Co3O4–BiPO4 on glassy carbon electrode (GCE). The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods showed a wide linear response to a concentration range, from 1.71 to 55.00 μM, and the epinephrine detection limit for this sensing system was found to be 1.334 μM. The Co3O4–BiPO4 electrode has very high selectivity towards the detection of epinephrine supported by an interference test. The epinephrine sensor seems very advantageous for future clinical health and medical sectors.
