Paper Title:
Structure and Antibacterial Properties of Ag-Doped TiO2 Porous Materials
  Abstract

Antibacterial Ag-doped TiO2 porous monolithics were firstly prepared by hybridization of polyethylene glycol, Ti(OC4H9)4 and AgNO3 via sol-gel method following by heat-treatment to remove the organic components. Thermogravimeter−differential thermal analysis, pore structure, infrared spectra, ultraviolet−visible spectra, release speed of silver ions into 30°C water and antibacterial properties of Ag-doped TiO2 samples made at different temperature were studied. The results showed that anatase phase and uniform pore structure can be formed after heated at 500°C. Ag+ ions from the samples heated at 500°C were stably released into water at 30°C up to 14 days. The material treated at 500°C has the best antibacterial property and can restrain Escherichia coli effectively.
