An Organic Solvent-Assisted Intercalation and Collection (OAIC) for Ti3C2Tx MXene with Controllable Sizes and Improved Yield

Highlights An organic solvent-assisted intercalation and collection (OAIC) approach for preparing Ti 3 C 2 T x (MXene) was developed. The features of OAIC approach are the low requirement for facility, gram-level preparation with remarkable yield and easy control over the dimension of Ti 3 C 2 T x flakes. The Ti 3 C 2 T x flakes prepared by OAIC approach showed the outstanding capacitive and rate performance. A good method of synthesizing Ti 3 C 2 T x (MXene) is critical for ensuring its success in practical applications, e.g., electromagnetic interference shielding, electrochemical energy storage, catalysis, sensors, and biomedicine. The main concerns focus on the moderation of the approach, yield, and product quality. Herein, a modified approach, organic solvent-assisted intercalation and collection, was developed to prepare Ti 3 C 2 T x flakes. The new approach simultaneously solves all the concerns, featuring a low requirement for facility (centrifugation speed
