performance owes to the absorption of number of dye molecules adsorbed on the
surface of nanocomposites as well as structure of the azo dye molecule.
Moreover, the presence of Fe 3 O 4 considerably enhanced the stability as well as
recyclability of nanocomposites. The disintegration pathway of azo dye was mainly
superoxide ion dependent. Transmission electron microscopy analysis was used for
the evaluation of structure which showed typical hexagonal wurtzite structure of
