Abstract

Herein we show that hydrazine intercalation into 2D titanium carbide (Ti₃C₂-based MXene) results in changes in its surface chemistry by decreasing the amounts of fluorine, OH surface groups and intercalated water. It also creates a pillaring effect between Ti₃C₂T_x layers pre-opening the structure and improving the accessability to active sites. The hydrazine treated material has demonstrated a greatly improved capacitance of 250 F g^-1 in acidic electrolytes with an excellent cycling ability for electrodes as thick as 75 μm.
