title: Exploiting electron storage in TiO2 nanoparticles for dark reduction of As(V) by accumulated electrons.
abstract: UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift. Direct evidence that the accumulated charges can drive the otherwise forbidden reduction of As(V) by conduction band electrons is presented.
