Dimensionality‐Driven Carbon Reconstruction Activates MXene Quantum Dots for Dechlorination

open access: yesSmall, EarlyView.
Finite Ti2CO2${\rm Ti}_2{\rm CO}_2$ MXene quantum dots exhibit a reconstruction‐induced activation mechanism absent in extended two‐dimensional MXenes. Carbon‐sublattice reconstruction generates electronically active motifs that facilitate charge redistribution and promote dechlorination of chlorinated hydrocarbons, revealing a new route for activating
