“…So, aer absorbing the MW, heat is produced which easily decomposes the doping source PA (as the decomposition temperature of PA is small like 150 ℃ (ref. 46)) and completes the doping process very quickly through rapid interfacial chemical interaction 41,47 without altering the lamella-like MXene structure. However; conventional heating is a slow process, where heat travels from the surface to the core and provides enough time to alter the Ti 3 C 2 T x phase structure to produce P-Ti 3 C 2 -An like TiP 2 O 7 , TiPO 4 , Ti(PO 3 ) 3 , Ti 3 (PO 4 ) 4 and many others.…”
