Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>SnO₂/TiO₂ nanocomposite thin films on glass plate and nickel screen were prepared by liquid phase deposition method. The degradation experiments of methylene blue (MB) indicated that the composite film exhibited higher photocatalytic activity than pure TiO₂ film. The improvement of the composite film photocatalytic activity can be attributed to the infiltration into TiO₂ lattice of nano-SnO₂. The optimal ratio of doped SnO₂ was 8%, with a 98·79% degradation rate in 5 h. The photocatalytic performance of SnO₂/TiO₂ film on nickel screen was obviously superior to that of nonconductive glass slide. The degradation of chemical oxygen demand (COD) was evaluated to investigate the mineralisation of MB. The COD removal rate increased with longer irradiation time and lagged behind the MB degradation rate.</p> </abstract>
