MXene-based hybrid nanomaterials in photocatalysis

MXenes possess unique properties, such as high electrical conductivity and suitable bandgap, due to which they are very useful in a large number of applications, such as, optoelectronic, energy storage, communications, biomedical, and environmental sectors. Because of their distinctive characteristics, the number of research articles and patents published has been growing quickly. Therefore, owing to its huge research interest, in this chapter we have discussed MXene-based hybrid nanomaterials and focused on their role in photocatalysis and discussed theoretical aspects describing the mechanism of photocatalysis to avoid redundancy. This chapter covers the role of MXenes in the photodegradation of dyes, water splitting, nitrogen fixation or reduction, carbon dioxide reduction, and organic synthesis. Moreover, it includes a detailed discussion on the advantages of MXenes for these applications, and the main challenges that limit their utilization and prospects are outlined.
