Novel materials for metal-air batteries: synthesis, characterization, and properties
In the present study, new efficient materials for metal-air batteries will be created by fabricating of manganese or other metal oxide and nitrogen-doped carbon quantum dot (N-CQdot) composites using chemical, electrochemical, and microwave synthesis methods. The kinetics of electrocatalytic reactions, including oxygen reduction (ORR) and oxygen evolution (OER), taking place in metal-air batteries, will be investigated using electrochemical and physicochemical methods. The surface morphology, structure, and composition of the formed materials will be studied in detail using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and inductively coupled plasma optical emission spectroscopy (ICP-OES), while the activity of created materials will be investigated using cyclic voltammetry (CV), linear sweep voltametry (LSV), the rotating disk electrode (RDE) technique, chronoamperometry (CA), and chronopotentiometry (CP).
