Highly Active TiO₂-MoS₂ Composite for Visible Light Photocatalytic Applications

Abstract:

Efficient visible light active TiO₂-Molybdenum sulphide (TiO₂-MoS₂) composites were prepared by solvothermal methodfrom titanium isopropoxide and commercial MoS₂ using N-methyl 2-pyrrolidone (NMP) and isopropanol (IPA) solvent mixture. Extended absorption band edge and enhanced visible light absorbance are supplemented intothe TiO₂-MoS₂ composites by this method. While TiO₂ shows ~48% visible light photodegradation of rhodamine B (RhB) the TiO₂-MoS₂(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.
