Abstract

Freestanding films containing nanocrystalline TiO2 and a suitable electron donor embedded in a cellulose matrix deoxygenate a closed environment (see Figure) upon UV illumination as a result of the photocatalytic properties of TiO2. This opens up the potential use of semiconductor photocatalysis in active packaging to achieve light-driven deoxygenation of closed environments.
