Strategies to Prepare 2D MXenes

MXenes have rapidly become a key focus in contemporary materials research, particularly because of their unique structural and electrical properties since their discovery. Consequently, they find application across various domains such as supercapacitors, batteries, and hydrogen storage. However, a significant challenge lies in optimizing existing methodologies or devising novel ones to enable high-quality, cost-effective, and scalable production, thereby broadening their potential applications. This section delves into the diverse range of top-down and bottom-up approaches employed for the production of 2D MXenes today. In addition to conventional wet-chemical synthesis methods, it elucidates innovative techniques like halogen etching, thermal reduction, UV-induced selective etching, and algae extraction, which have surfaced in recent years. Furthermore, it provides intricate insights into the optimization of process parameters within the chemical vapor deposition method utilized for synthesizing 2D MXenes.
