Quantitative Assessment on the Water Change of 2D Ti 3 C 2 T X MXene Under Alkali Treatment

MXene after varied alkali treatments displays a shift of capacitance dependence from upon basal spacing under slow scan rate to upon F content under fast scan rate. The findings further deepen the understanding of water dynamics and structural changes of the 2D layered MXenes during alkali treatment, and should shed light in fine-designing the dehalogenation strategies to achieve desired properties.
