The carbon nitride‐supported zinc oxide (CNZO) nanocomposite was synthesized through a high‐temperature synthesis method, resulting in zinc oxide nanoparticles with an average size of ~ 44 nm, dispersed on a carbon nitride matrix. X‐ray diffraction confirmed the formation of the hexagonal wurtzite phase of zinc oxide, with a space group of P63mc. X‐ray photoelectron spectroscopy and Fourier‐transform infrared analysis further verified the presence of both zinc oxide and carbon nitride. The CNZO nanocomposite served as a catalyst for the electrochemical detection of dopamine, achieving limit of detection and sensitivity of 2.66 µM and 6.23 µA.µM ‐1.cm ‐2 respectively
