Abstract

The rise in industrialization and extensive agricultural practices have resulted in widespread release of toxic contaminants into surface and groundwaters. These include organic contaminants such as dyes, antibiotics, pharmaceuticals; inorganic contaminants such as heavy metal ions (HMIs) and biological contaminants. They are recognized to pose adverse effects on environment as well as humans. To solve this problem, many researchers employed photocatalysis technique as the most favorable process for environmental remediation due to its cost-effectiveness and energy-saving.. Nowadays, various 2D nanomaterial-based photocatalysts are widely applied for the degradation of water contaminants using photocatalysis method. In this chapter, some of the potential 2D nanomaterial photocatalysts based on transition metal dichalcogenides (TMDs), MXenes and Phosphorene nanostructures with high surface/volume ratio, greater degradation efficiency, abundant active sites, compatible functional groups and diverse band structures are presented. This chapter concisely describes the impact of organic contaminants on living systems, followed by the synthesis and properties of 2D nanomaterial-based photocatalysts. The photocatalytic degradation of various dyes and antibiotics using 2D nanomaterial-based photocatalysts including the mechanistic pathway is also discussed. Finally, the future outlooks and challenges associated with the application of 2D nanomaterial-based photocatalysts in degradation are mentioned.
