In this work, we have prepared MoS<sub>2</sub> nanoflakes modified TiO<sub>2</sub>
nanoparticles (MoS<sub>2</sub>-TiO<sub>2</sub> nanocomposite) with varying concentration
of MoS<sub>2</sub> (2.5–10 wt.%) by a two-step hydrothermal synthesis method involving
specific preparation conditions for the TiO<sub>2</sub> nanoparticles and MoS<sub>2</sub>
nanoflakes. The prepared samples were characterized by X-ray diffraction (XRD), Raman
spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy
(TEM), energy dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy
(XPS) techniques. The photocatalytic activity of the pristine TiO<sub>2</sub> nanoparticles
and MoS<sub>2</sub>-TiO<sub>2</sub> nanocomposite samples were evaluated by examining
the photocatalytic degradation of Rhodamine B (RhB). The photoelectrochemical activity
of these samples were measured by performing solar water splitting experiments under
visible light irradiation. It was observed that the MoS<sub>2</sub>-TiO<sub>2</sub>
nanocomposite with 7.5 wt.% MoS<sub>2</sub> exhibits highest photocatalytic and photoelectrochemical
activity as it has the optimum amount of MoS<sub>2</sub> nanoflakes which probably
minimizes the recombination of photogenerated charge carriers as compared to other
concentrations of MoS<sub>2</sub> in MoS<sub>2</sub>-TiO<sub>2</sub> nanocomposite
and pristine TiO<sub>2</sub> nanoparticles. In addition, a rather high photocatalytic
reaction rate constant was observed for MoS<sub>2</sub>-TiO<sub>2</sub> nanocomposite
with 7.5 wt.% MoS<sub>2</sub> nanoflakes. |
