The photocatalytic semiconductor titanium dioxide (TiO2) can be used in the degradation of organic pollutants such as pharmaceuticals in water. A problem with using TiO2 on its own is that is can agglomerate in water and is very hard to remove from the water after treatment. To solve this problem nano-TiO2 can be immobilised onto a host material, such as activated carbon, as a catalytic support, leading to the development of Integrated Photocatalytic Adsorbents (IPCAs). A promising new nanomaterial is TiO2 nanotube (TNT). Using such nanomaterials in water treatment is relatively new; using TNTs in combination with Graphene is newer still. Mixed results using these IPCAs for pollutant removal has been reported in the literature and confirmed in our work. This presentation explores these issues and outlines developments in the area.
