| Description: | Speaker Nikos Katsarakis Affiliation IESL, FORTH and TEI of Crete, Greece Title Metal oxide thin films and nanostructures for energy-control and environmental applications Location Department of Physics Bldg., Voutes, 3rd floor Seminar Room Time 16:00 Language English Abstract Metal oxide thin films and nanostructures offer a wide range of potential applications including photocatalysis of organic pollutants, "self-cleaning" surfaces and energy-efficient glass windows. We have applied simple, low-cost, environmental-friendly chemical techniques like sol-gel, spray pyrolysis, chemical vapour deposition and solution-based approaches to grow metal oxide thin films and nanostructures on glass, sapphire and plastic substrates. In particular, TiO2, TiO2:SiO2, ZnO, WO3 and VOx thin films and nanostructures have been grown by chemical methods on various substrates at relatively low temperatures and their structural, morphological and optical properties were investigated. Moreover, the metal oxide samples were comprehensively studied with respect to their photocatalytic efficiency regarding the degradation of stearic acid, their "self-cleaning" properties and electrochemical response. Several issues, including how growth parameters (precursor solution, temperature, growth time etc) affect metal oxide properties as well as the potential for technological applications, will be discussed. |
