as Rhodamine B (He et al. 2016). Most of the photocatalytic agents are various types
of NCs (Abdullah et al. 2016; Bhunia and Jana 2014; DePuccio et al. 2015; Abdalhay et al. 2015; Lin et al. 2012; Zhang et al. 2014). The rest of the photocatalytic
agents are either NPs (Houas et al. 2001; He et al. 2016) or modified NPs (Bumajdad
and Madkour 2014).
Most recent work (Table 3) indicates that only scarcely Mg(OH) 2 NPs (Liu et al.
2015) and nanoflowers (NFs) (Cao et al. 2012; Yang et al. 2016) are used for removal
of Pb(II), Cd(II) while a singular work (Das et al. 2017) attempts removal of Cu(II) by
nanoplatelet (NPL) of Mg(OH) 2 . Similarly, there is another attempt (Das et al. 2018)
that uses 3D self-assembled Mg(OH) 2 nanoplatelet assembly to degrade MB dye by
photocatalysis. Therefore, the objective of the present work is to use the optimally
designed microstructure of Mg(OH) 2 for dual purpose of removal of Cu(II) ions and
degradation of MB dye.
