This paper reports the fabrication of self-supporting
three-dimensional
ZnIn<sub>2</sub>S<sub>4</sub>/PVDF–poly(MMA-<i>co</i>-MAA) (ZIS/Polymer) composite mats with hierarchical nanostructures
by a simple combination of an electrospinning technique and a hydrothermal
process and their high photocatalytic activity. The characterization
results show that ZnIn<sub>2</sub>S<sub>4</sub> (ZIS) nanosheets with
a thickness of about 20 nm distribute uniformly on the surface of
the nanofiber polymers to form mats. The coverage density of the ZIS
nanosheet coating on the surface of the polymer mats could be controlled
by simply adjusting the amount ratios of feeding reactants to polymers.
Furthermore, the growth process of ZIS coating is investigated based
on time-dependent experiments. The obtained ZIS/Polymer heteroarchitectures
show high photocatalytic property and stability to degrade methyl
orange (MO) because of the formation of hierarchical nanostructures,
which might improve the adsorption and catalysis of the dyes. Due
to the self-supporting property of the mats, the ZIS/Polymer mats
could be laid or hung conveniently anywhere under solar irradiation
and recycled easily, which provides a solution to the separation problem
for conventional catalysts that are small in size. The study may open
a new way to build hierarchical device fabrics with optical and catalytic
properties.
