Freestanding films containing nanocrystalline TiO 2 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 TiO 2 . This opens up the potential use of semiconductor photocatalysis in active packaging to achieve light‐driven deoxygenation of closed environments.
