Competitive Advantages
- Enhanced absorbance of TiO2 into visible spectrum
- Reduced time for complete elimination of the bacteria
- Efficiently disinfects water
Summary
USF inventors have synthesized a novel photocatalytic nanomaterial composed of molybdenum disulfide (MoS2) doped TiO2. When integrated with SODIS, this nanomaterial can enhance the photocatalytic properties of TiO2 . Doping with low concentrations of MoS2 enhances the absorption of light by TiO2 into the visible spectrum and increases its absorbance into the UVB/UVA range without inhibiting its inherent oxidative properties. This results in a reduction to the time required for full elimination of E. coli from portable water within the SODIS platform from 150 minutes to 120 minutes, compared to pure TiO2 nanomaterial.
