Physical properties and photocatalytic performance of TiO2 coated stainless steel plate

This research was conducted for the development of TiO2 thin film coated st ainless steel useful in environmental and sanitary fields such as removal o f indoor air pollutants and prevention of harmful microorganisms in the kit chen and bathroom. For this purpose, the research was focused on the examin ation of physical properties of coated surfaces as well as the photocatalyt ic performance of the steel plates. The coated steel's cohesiveness and ant i-corrosion effect were good enough to be used even in the hard environment s. To test the photocatalytic performance of the TiO2 thin film coated stai nless steel plate, photodegradations of m-xylene, a typical air pollutant p roduced by automobiles, and E. coli, under 365 nm UV irradiation, were cond ucted. The TiO2 coated stainless steel plate considerably enhanced the degr adation efficiencies of m-xylene and E. coli.
