“…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. As mentioned in the Introduction section, 35,36 in the presence of oxygenated functional groups and a longer reaction time, Ti-based materials are highly prone to form titanium phosphates through a phase change reaction and it might be the case with the conventional heating of Ti 3 C 2 T x in the presence of P doping sources as well. So, the choice of doping source, homogeneity of the mixture, and selection of a suitable heating method are extremely important to develop titanium phosphate free P-Ti 3 C 2 with adequate P doping to boost the electrochemical storage performance of Ti 3 C 2 T x .…”
