Research Progress of Characteristics and Applications of Two-dimensional Nanomaterial MXenes

Two-dimensional layered transition-metal carbonitrides (MXenes) have attracted increasing attention, and showed excellent performance in the field of energy, catalysis, environment due to the intriguing crytal characteristics and structure properties. In this review, we systematically introduce the MXenes’ unique stability, mechanical properties, electronic properties, magnetic properties, optical properties, thermoelectric properties, ferroelectric and piezoelectric properties . Meanwhile, we summarize and analyze the latest progress and research results on the application of MXenes in the field of batteries, electrochemical capacitors and catalysis. Finally, this review concludes with invigorating perspectives, outlooks and formidable challenges in the future development of MXenes and MXene-based composite materials.
