Inorganic materials for photocatalytic water disinfection

Zhang, Dieqing, Li, Guisheng, Yu, Jimmy C.·2010·Journal of Materials Chemistry

Abstract

Traditional water disinfection methods such as chlorination and ozonation inevitably form harmful disinfection by-products (DBPs). UV irradiation is a safe alternative but it is very energy intensive. It makes perfect sense to enhance the utilization of photons by integrating engineered photocatalytic nanostructures in the treatment system. UV-light active photocatalytic inorganic nanomaterials, such as titania, are capable of inactivating various bacteria and viruses. They work by generating powerful but short-lived oxygen-based radicals upon irradiation. Unlike conventional chemical disinfectants, the antimicrobial nanomaterials are not consumed in the process. Photocatalytic water disinfection is a green technology because the same materials can be used over and over again. This paper reviews the recent progress in the fabrication of inorganic nanomaterials for photocatalytic water disinfection. A variety of UV and even visible-light driven water disinfection systems are introduced. Their advantages and limitations as well as the antimicrobial mechanisms are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
