3. Full text summary

Here, the author takes Ti3C2Tx etched by the HF/HCl method as an example to describe the safety process and procedures for the synthesis of MXenes. Part of the hazards from the synthesis of ti3alc2 are high-temperature powder and hydrochloric acid washing. When synthesizing Ti3C2Tx from Ti3AlC2 using HF-based etchant, the main safety issue is the handling and use of HF-containing solutions. Before conducting experiments, it is vital to fully understand all risks, wear appropriate personal protective equipment, use engineering control measures as much as possible, and always conduct experiments with other people in the laboratory. Through the procedures outlined in the article, researchers will be able to produce high-quality MXenes in a safe and reproducible manner.
