In this work, MXene and composite rGO/MXene electrodes were prepared and characterized in two- and three-electrode systems as well as by using an optical microscope. In addition, the aim of the work was to obtain and characterize a stable and free-standing material that will be suitable as a support for zinc in zinc-ion water batteries. The rGO/MXene composite electrodes were prepared by electrochemical reduction of graphene oxide (GO) in the GO/MXene composite. It was found that the reduction degree depends on whether pure GO or GO in the composite is reduced. In order to examine the test in a two-electrode system, MXene and rGO/MXene papers were prepared, on which zinc was subsequently deposited. The properties of MXene and rGO/MXene electrodes were tested using chronoamperometry, cyclic voltammetry, galvanostatic polarization in 2 M ZnSO4 solution. The morphological characterization of MXene and rGO/MXene layers was conducted using an optical microscope. By cyclic voltammetry, it was determined that all prepared electrodes exhibit capacitive behaviour. It was also found that the electrode containing MXene is not stable above 0,4 V. Testing of different MXene and rGO/MXene electrodes in a three-electrode system indicated that the rGO/MXene-R2 electrode has better properties compared to pure MXene. The better stability of the composite rGO/MXene electrode compared to pure MXene was also confirmed with an optical microscope. The rGO/MXene composite proved to be more suitable for zinc deposition than MXene. During zinc deposition in the two-electrode system, on MXene-a and rGO/MXene paper, nucleation maxima were observed at shorter times. Therefore, the characterization of zinc nucleation on the mentioned materials was carried out by Beweick, M.Fleischman and H.R. Thirsk, and Scharifker-Hills theoretical models. By comparing the results of chronoamperometry with theoretical models for nucleation processes, 3D instantaneous nucleation was determined. Testing of a symmetrical zinc cell with MXene-Zn and rGO/MXene-Zn active materials showed that the prepared active materials lower the zinc stripping and plating overvoltage.
