Hydrothermal synthesis of MoS nanosheet loaded TiO nanoarrays for enhanced visible light photocatalytic applications
A molybdenum disulfide (MoS 2 ) nanosheet-decorated titanium dioxide (TiO 2 ) NRA heterojunction composite was fabricated successfully through a two-step hydrothermal approach. Microstructures and optical properties of specimens were characterized by field-emission scanning electron microscopy, X-ra...

| description | A molybdenum disulfide (MoS

2
) NRA heterojunction composite was fabricated successfully through a two-step hydrothermal approach. Microstructures and optical properties of specimens were characterized by field-emission scanning electron microscopy, X-ray diffractometry, X-ray photoelectron spectroscopy, and ultraviolet-visible spectroscopy. The gaps of the TiO
2
nanorods have been filled with tiny MoS

nanosheets, which can increase the surface area of MoS

NRA composite thin films. In addition, the photocatalytic activity of the thin films were measured and discussed in greater detail. The appropriate hydrothermal reaction temperature of MoS
2
is important for the growth of perfect MoS

/TiO

NRA composites with significantly enhanced photocatalytic performance. The photodegradation rate and
k
value of MoS
2
-220/TiO
2
are 86% and 0.0105 min
−1
, respectively, which are much larger than those of blank TiO
2
. The enhanced photocatalytic performance could be attributed to the higher visible light absorption and the reduced recombination rate of photogenerated electron-hole pairs.
