Antibacterial paper from photocatalytic TiO2

The feasibility of producing paper with antibacterial properties based on the photocatalytic activity of TiO2 (anatase) was evaluated. Eighty percent of the bacteria deposited onto photocatalytic paper, were killed by thirty minutes exposure to 25 W/m² UVA. To achieve this effect it was determined that the water content of the paper must be 40% or greater, and the TiO2 must be located on the exposed surface because UV intensity is attenuated by …
