erspectives of 2D MXene-based materials for self-powered smart gas sensors

Abstract

Among the materials at the forefront of the development of gas sensors, 2D MXene-based materials have garnered attention for their exceptional properties and potential in this application. Correspondingly, their expanding significance in the domain of self-powered smart gas sensors continues to make a strong impression on us. This perspective paper aims to provide a comprehensive overview of the exciting developments in the use of 2D MXene-based materials for self-powered smart gas sensors. This review deals with the advantages of MXenes for gas sensor applications, explores the working principles of selfpowered gas sensor devices, investigates various types of energy sources used to power these devices, examines current advances in MXene-based materials for self-powered smart gas sensors and discusses the roles of MXene-based materials both as power sources and active sensing materials in these sensors. To conclude, this review goes through the insights of the contemporary state of the field and indicates a prospective avenue for further investigation within this field of study.
