ABSTRACT

Two-dimensional nanomaterials (2D NMs) have triggered intensive research consideration owing to their intriguing properties such as unique ultra-thin structures, elevated surface area, fascinating morphology, high flexibility, cost-effectiveness, high electrical as well as thermal conductivity and exceptional mechanical and chemical stability. These appealing features make 2D NMs the most desirable candidates for energy applications including photocatalysis, supercapacitors, solar cells, lithium-ion batteries, fuel cells, CO2 reduction, water splitting and many more. This chapter offers a brief overview of recent advancements in 2D NMs such as graphene, MXenes, graphitic carbon nitride (g-C3N4), transition metal dichalcogenides, and layered transition metal oxides and their importance in energy-related applications. Finally, we also discussed remaining challenges and future outlooks in these research areas.
