ABSTRACT

At present, nanotechnology has been growing tremendously, and has therefore, attracted considerable interest in the development of nanostructured materials with extraordinary electronic, chemical, and optical properties for chemical detection. Till now various nanostructured materials in the form of 0D, 1D, 2D and 3D have been explored for chemical sensing. This is a class of materials widely investigated for chemical detection because of their fascinating electro-optic and morphological properties. From a device point of view, these materials exhibit low-power consumption, high mobile charge carriers, low-weight, high stretchability and flexibility, good mechanical stability, excellent optical transparency, and good environmental stability, etc. The external layer of TMDCs contains chalcogen atoms with a lone pair and so, it gives a well compounded constancy. MXenes show remarkable optical properties, and therefore, are widely used in photocatalysis, photoconductive and opto-electric sensors and have also been tested to develop a highly conducive transparent electrode.
