Abstract
This research was conducted for the development of TiO2 thin film coated stainless steel useful in environmental and sanitary fields such as removal of indoor air pollutants and prevention of harmful microorganisms in the kitchen and bathroom. For this purpose, the research was focused on the examination of physical properties of coated surfaces as well as the photocatalytic performance of the steel plates. The coated steel's cohesiveness and anti-corrosion effect were good enough to be used even in the hard environments. To test the photocatalytic performance of the TiO2 thin film coated stainless steel plate, photodegradations of m-xylene, a typical air pollutant produced by automobiles, and E. coli, under 365 nm UV irradiation, were conducted. The TiO2 coated stainless steel plate considerably enhanced the degradation efficiencies of m-xylene and E. coli.
