This article presents a perspective on using MXenes for energy harvesting from various sources in the environment. It systematically introduces the characteristics of MXenes for energy capturing and summarizes the preparation strategies of MXenes and their derived nanostructures tailored toward such applications. The harvesting mechanism of different energy sources is discussed, and recent progress in MXene-based nanostructures for energy harvesting is introduced. The existing challenges and future directions of MXene-based nanostructure for energy harvesting are also presented.
Energy harvesting modules play an increasingly important role in the development of autonomous self-powered microelectronic devices. MXenes (i.e., 2D transition metal carbide/nitride) have recently emerged as promising candidates for energy applications due to their excellent electronic conductivity, large specific surface area, and tunable properties. Herein, a perspective on using MXenes to harvest energy from various sources in the environment is presented. First, the characteristics of MXenes that facilitate energy capturing are systematically introduced and the preparation strategies of MXenes and their derived nanostructures tailored toward such applications are summarized. Subsequently, the harvesting mechanism of different energy sources (e.g., solar energy, thermoelectric energy, triboelectric energy, piezoelectric energy, salinity-gradient energy, electrokinetic energy, ultrasound energy, and humidity energy) are discussed. Then, the recent progress of MXene-based nanostructures in energy harvesting, as well as their applications, is introduced. Finally, opinions on the existing challenges and future directions of MXene-based nanostructure for energy harvesting are presented.
