dc.description.abstract | In this work, Ag-TiO2 nanocomposites were prepared via the sonochemical deposition of Ag nanometals on TiO2 nanoparticles. The size of deposited Ag nanometals was ranged in 13 nm and the number of Ag nanometals deposited on TiO2 increased in proportion to the dosage amounts of Ag precursors. As-prepared Ag-TiO2 was loaded on the sterilized agar plate together with an aliquot volume of diluted E-coli, followed by 30 min irradiation of the solar simulated light (6001800 μw/cm2). Finally, the agar plate was incubated for 24 h at 37°C and the number of survived colonies were counted. It was experimentally confirmed that Ag-TiO2 exhibited the higher antimicrobial activity than that of pure TiO2, based on measuring the colony number of control sample. The survived colony numbers on the agar plate decreased with the increase of dosage amounts of Ag-TiO2 and the irradiated intensity of solar simulated light for 30 min before incubating. The increase of Ag nanometal doposition induced the progressive enhancement of antimicrobial activity, but rather reduced the photocatalytic activity of Ag-TiO2 probably due to the excessive presence of Ag nanometals on TiO2 matrix. © 2014 The Korean Society of Industrial and Engineering Chemistry.
