Abstract
|
Recently, ultrathin two-dimensional (2D) materials, known as nanosheets, have attracted great interest
owning
to their ultimate structural and desirable physical, chemical, thermal, electrical, and optical
characteristics.
Various potential applications of 2D nanomaterials have been reported in electronics/
optoelectronics,
electrocatalysis, batteries, supercapacitors, solar cells, sensors, photocatalysis, and other
environmental
processes. Modification of polymeric membranes using nanosheets is increasingly
reported
in the literature. The incorporation of inorganic nanostructured additives, such as metal oxide
and
metal hydroxide nanosheets, can impart desired characteristics to the surface and matrix of the
membrane
and improves its filtration performance. This review summarizes the preparation methods of
the
metal oxide and metal hydroxide nanosheets, with a special emphasis on the recent advances in this
field.
The structural and physicochemical properties of the 2D nanosheets have been discussed, and after
that,
the applications of these nanosheets for modification of polymeric membranes are presented with a
focus
on the membranes used for environmental applications. Finally, the existing challenges and future
perspectives
for synthesis and membrane-related applications of 2D metal oxide and metal hydroxide
nanosheets
are discussed.
