In this study, MXene Ti3C2X2 and BaMnO3 nanoparticle-doped MXene particles were prepared by HF etching mechanism and hydrothermal method. Scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDX), transmission electron microscopy (TEM), and X-ray diffraction (XRD) methods were utilized for the characterization of as-synthesized catalysts. The presence of BaMnO3 nanoparticles in the catalyst system was confirmed by XRD and EDX spectra. The catalytic activity of the BaMnO3/MXene catalyst for hydrazine electrooxidation was investigated by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) in a basic medium. The mass activities of bare MXene and BaMnO3/MXene for hydrazine electrooxidation were determined as 309.5 and 731.7 mA mg−1, respectively. Increasing specific activity attributed to the improvement of the kinetics for the hydrazine electrooxidation reaction on MXene with the addition of BaMnO3. BaMnO3/MXene has been found to have lower charge transfer resistance and higher electrocatalytic activity than MXene. Novel BaMnO3/MXene catalyst showed super performance for hydrazine electrooxidation.
