Effect of terminal groups on the degradation stability of Ti

MXenes are 2D nanomaterials which have gained considerable attention from researchers since their discovery in 2011. However, the propensity of these 2D nanomaterials to degrade affects their shelf life. While many studies have focused on the external factors affecting the degradation of MXenes, the effect of internal factors such as terminal groups is not well understood. In this paper, we use -Br and -Cl terminations as model terminal groups to compare the degradation stability of MXenes. From our experiments we observe that -Br terminated ML-Ti
