Immobilization and Photocatalytic Activity of TiO₂ Nanoparticles on Porous Aluminium Foil

Abstract

TiO₂ nanoparticles (TiO₂ NPs) have been immobilized on the pore wall of porous aluminium foil. Compared with the aluminium foil and the film of TiO₂ NPs deposited on the glass substrate, the aluminium foil with TiO₂ NPs displays higher photoactivity for degradation of methyl orange. Meanwhile, the photocatalytic activity of the aluminium foil with TiO₂ NPs possesses good reproducibility.
