Overview of Pathogenic Micro-Organisms Destruction in Contaminated Water by Oxide Photocatalysis

摘要

The titanium dioxide (TiO_2) is a semiconductor oxide photocatalys, which is chemically and biologically inert but exhibits excellent photolytic activity in the ultraviolet (UV) region. Progress in photocatalytic water disinfection requires understanding both concepts of TiO_2 semiconductor as well the biochemistry of microorganisms. The advantage and disadvantage for current water purifications are discussed. Finally, the photocatalytic reactions to water disinfection and detoxification using solar energy.
