Abstract

High-quality amino-functionalized Ti₃C₂T_x MXene (alk-MXene-NH₂) nanosheets were successfully synthesized by a facile alkalization-grafting modification for lead adsorption. The alk-MXene-NH₂ achieved the highest BET specific area among all MXene-based adsorbents, and the generated abundant –NH₂, –OH and –ONa complexing groups exhibited strong interactions with lead ions, resulting in attractively high adsorption capacity.
