The mixed design of multiphase transition metal oxides is one strategy for obtaining electrode materials. The MnCr2O4/Cr2O3 mixture has been synthesized using a simple and inexpensive coprecipitation method. XRD analysis revealed the formation of the MnCr2O4/Cr2O3 mixture. The electrochemical properties of the MnCr2O4/Cr2O3 mixture were studied using cyclic voltammetry. MnCr2O4/Cr2O3 mixture showed redox potential in the potential range -0.3 - 1.0 V (vs Ag/AgCl). Therefore, mixed electrodes are predicted as candidates for application as electrode materials. The electrochemical properties of MnCr2O4/Cr2O3 need to be compared with the single phase of Cr2O3 and Mn Cr2O4 so that it can be seen whether the mixed material of the two TMOs has a higher electrochemical potential compared to individual TMOs. © 2023 American Institute of Physics Inc..
