Abstract This chapter defines the two-dimensional (2D) nanomaterials that have
been used in separation science. Then, chapter summaries can be found at the end
of this chapter.

1 Background
Industrialization, urbanization, population growth, etc., have severely contaminated
freshwater resources. It is due to the addition of macro-, micro- [1] and nanopollutants [2] into the water bodies. Among these, nanoplastics and nanoparticles
have recently become emerging water pollutants of global importance. These pollutants have detrimental effects not only on human health, but also on aquatic flora
and fauna [3]. Huge investment is necessary each year due to these polluted water
consequences. Therefore, water purification using state-of-the-art technologies is
necessary for an unlimited safe water supply [4]. Nowadays, these technologies need
novel materials, especially two-dimensional (2D) nanomaterials (NM), due to their
atomic-scale thickness, nano-sized pores, high surface area, stability, and high purification ability [5]. It has been around 160 years that scientists have studied layered
materials. However, very recently, they have tried to figure out the actual uses of
these materials for various technological applications [6]. Most of the bulk materials, for example, three-dimensional (3D) graphite, when thinned into nanoscale,
for example, graphene, and these thinnest NMs are called 2D nanosheets at their
physical limit as shown in Fig. 1.
Since 1859, many occasional attempts were taken to study graphene, but it is
widely synthesized and used after 2004 when Professor Sir Andre Geim and Professor
