Selective grafting of phosphorus onto Ti₃C₂T_<i>x</i> MXene enables a two-proton process and enhanced charge storage

Abstract

Phosphorus atoms are selectively doped onto Ti 3 C 2 T x MXene, leading to solely P–O doped species, which serve as new active sites to enable two-proton bonding/debonding process to boost charge storage ability of MXene.
