Titanium Dioxide Nanostructured Coatings: Application in Photocatalysis and Sensors

This paper presents some of the research work taking place at the University of Ulster investigating preparation, characterisation and application of nanostructred TiO2. Four exemplars are used to demonstrate the potential applications of these materials i.e. photocatalytic disinfection of water containing chlorine resistant microorganisms, photocatalytic ‘self-cleaning’ of surfaces contaminated with protein, transducers for electrochemical biosensors and finally new opportunities presented by electrochemical growth of TiO2 aligned nanotubes.
