A “two-birds-one-stone” strategy to enhance capacitive deionization performance of flexible Ti₃C₂T_<i>x</i> MXene film electrodes by surface modification

Abstract

A dual-function strategy is proposed that uses sodium ascorbate to modify Ti 3 C 2 T x MXene for flexible and free-standing electrodes for capacitive deionization, enhancing its oxidation resistance and salt adsorption capacity.
