Synthesis of functional nanomaterials which could yield high photocatalytic activities under the visible light (typically >400 nm) is preferred for commercial applications. As part of an industry led project to develop efficient surface coatings, our research were focused in the development of new nano-catalysts for antibacterial applications. TiO2 Anatase phase stable up to the sintering temperature of the substrates (e.g., bathroom tile, sanitary ware, etc.) is most suitable for building materials applications. Thermal stability of the anatase phase at elevated temperatures is one of the industrial requirements for making such coatings on ceramic based surfaces. Anatase phase which is thermally stable up to the sintering temperature of the ceramic materials (e.g., bathroom tile, sanitary ware, etc.) is hugely beneficial for building materials applications. The preparation of novel photo-catalytic materials by modifying the band-gap using various dopants such as F, S, N and C will be discussed.


Prof. Suresh C. Pillai obtained his PhD from Trinity College Dublin and then performed his postdoctoral research at California Institute of Technology (Caltech), USA. Upon completion of this appointment he returned to Trinity College Dublin as a Research Fellow before joining CREST-DIT as a Senior Scientist in April 2004. He has joined IT Sligo in 2013 as a senior lecturer in nanotechnology and currently heads the Nanotechnology and Bio-Engineering Research Group. He is an elected fellow of the UK’s Royal Microscopical Society (FRMS) and the Institute of Materials, Minerals and Mining (FIMMM). He has also completed an executive MBA from Dublin City University, in 2009. He was responsible for acquiring more than €5 million direct R&D funding. He was the recipient of many awards, such as ‘the 2019 Boyle-Higgins’ award from the Institute of Chemistry Ireland. He has published several scientific articles in leading peer reviewed journals has contributed to several book chapters, has presented in more than fifty international conferences and has delivered over forty international invited talks. He is an editor for the journal Environmental Science and Pollution Research (ESPR, Springer) and Editororial Board Member for the Chemical Engineering Journal and Applied Catalysis B (Elsevier).
