Utilization of sunlight for water detoxification can occur by direct absorption, sensitized production of active oxygen species, iron ion-mediated processes, heterogeneous photocatalysis on semiconductors. This article assesses the state of development, the advantages and limitations, and the barriers to overcome for practical applications of solar technologies for water purification, with particular attention to heterogeneous photocatalysis.

Abstract
Utilization of sunlight for water detoxification can occur by direct absorption, sensitized production of active oxygen species, iron ion-mediated processes, heterogeneous photocatalysis on semiconductors. This article assesses the state of development, the advantages and limitations, and the barriers to overcome for practical applications of solar technologies for water purification, with particular attention to heterogeneous photocatalysis.
