TL;DR: In this article, a review focusing on the heterogeneous photocatalytic treatment of organic dyes in air and water is presented, which includes historical aspects, dark adsorption of the dye on the semiconductor surface and its role in the subsequent photoreaction, semiconductor preparation details, photoreactor configurations, photooxidation kinetics/mechanisms and comparison with other Advanced Oxidation Processes (e.g., UV/H 2 O 2, ozonation, UV/O 3, Fenton and photo-Fenton reactions), visible light-

TL;DR: Irradiation of suspensions of Escherichia coli and TiO[sub 2] (anatase) with UV-visible light of wave-lengths longer than 380 nm resulted in the killing of the bacteria within minutes and oxygen was found to be a prerequisite for the bactericidal properties of the photocatalyst.

TL;DR: In this paper, the authors highlight the advances that have been made and identify some of the gaps in our current knowledge of these materials and discuss size quantization effects and semiconductor quantum dots.

TL;DR: A companion review of photoelectrochemical methods for environmental applications is presented in this article, where new electrode materials for environmental application are described, and applications of these methods in the drinking water industry, and for disinfection scenarios are discussed.

TL;DR: In this paper, the authors define and classify Pollutants, and present current methods for Pollutant Analyses, including current, charge, and potential, as well as current and potential charge and mass transport in an electrochemical cell.
