MXene nanomaterials: Synthesis, properties and applications in energy and environment sector

MXene composed of transition metal carbides, nitrides, or carbonitrate, is the most ornamented and rapidly expanding two-dimensional (2D) material. Due to its exceptional qualities, including its adjustable band gap, high thermal conductivity, charger mediator, superior electrical conductivity, and environmental adaptability, MXene is now attracting the interest of researchers. MXene possesses a strongly hydrophilic surface, ion exchange capabilities, and durable surface functional groups. This study provides an overview of the synthesis, properties, and prospective applications of MXenes in energy, sensing and environment sectors. Firstly, this article provides a brief overview of the MAX phase (including its characteristics and recent advancements) and MXene. Then, we thoroughly investigated the different etching techniques used in the synthesis of MXene. Moreover, various properties of MXenes, such as structural, optical, mechanical, magnetic, and electronic characteristics have been investigated. In addition, the potential applications of MXenes in various dynamic fields such as supercapacitor, energy storage and conversion, water splitting, electrochemical sensors and waste water treatment has been explored symmetrically. This study also focuses on the current progresses and future prospective relating to MXene, which will surely assist the scientists who are doing work in areas of academia and material sciences.
