Herein we show that hydrazine intercalation into 2D titanium carbide (MXene) results in changes in materials surface chemistry by decreasing the amount of OH surface groups and intercalated water. It also creates a pillaring effect between Ti3C2Tx layers pre-opening the structure and improving accessability to active sites. The hydrazine treated material has demonstrated a greatly improved capacitance of 250 F/g in acidic electrolyte with an excellent cycling ability for electrodes as thick as 75 μm.
