Highly Active TiO<sub>2</sub>-MoS<sub>2</sub> Composite for Visible Light Photocatalytic Applications
Abstract
Efficient visible light active TiO 2 -Molybdenum sulphide (TiO 2 -MoS 2 ) composites were prepared by solvothermal methodfrom titanium isopropoxide and commercial MoS 2 using N-methyl 2-pyrrolidone (NMP) and isopropanol (IPA) solvent mixture. Extended absorption band edge and enhanced visible light absorbance are supplemented intothe TiO 2 -MoS 2 composites by this method. While TiO 2 shows ~48% visible light photodegradation of rhodamine B (RhB) the TiO 2 -MoS 2 (0.24) exhibits~74% of degradation. In addition to the visible light enhancement, very high surface area and reduced charge transfer resistance at the interfaces are attributed to the enhanced activity of the composite.
