Molybdenum titanium carbide (Mo₂TiC₂T _<i>x</i> ) MXene coated carbon electrodes for vanadium redox flow batteries.

ABSTRACT: Carbon-based electrodes are the most commonly used electrode materials for vanadium redox flow batteries (VRFBs). Due to the use of aqueous electrolytes in VRFBs, the first challenge is the hydrophobicity properties of carbon-based electrodes, and the second challenge is that the desired redox reaction on the positive side, VO²⁺/VO₂ ⁺, competes with the oxygen evolution reaction. Therefore, a proper surface treatment is needed. In the present work, three different brands of carbon papers (Sigracet 28AA, Toray 060, and Freudenberg H23) were treated with heat treatment and an MXene coating. For the latter, a two-dimensional (2D) molybdenum titanium carbide (Mo₂TiC₂T _x ) was chosen and the drop-casting method was used fo
