Highly Active TiO sub(2)-MoS sub(2) Composite for Visible Light Photocatalytic Applications

Efficient visible light active TiO sub(2)-Molybdenum sulphide (TiO sub(2)-MoS sub(2)) composites were prepared by solvothermal methodfrom titanium isopropoxide and commercial MoS sub(2) using N-methyl 2-pyrrolidone (NMP) and isopropanol (IPA) solvent mixture. Extended absorption band edge and enhanc...

Summary:Efficient visible light active TiO sub(2)-Molybdenum sulphide (TiO sub(2)-MoS sub(2)) composites were prepared by solvothermal methodfrom titanium isopropoxide and commercial MoS sub(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 sub(2)-MoS sub(2) composites by this method. While TiO sub(2) shows ~48% visible light photodegradation of rhodamine B (RhB) the TiO sub(2)-MoS sub(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.
