Abstract: Titanium dioxide (TiO2) nanoparticles were dispersed in a cellulose nanofiber (CNF) matrix to form composite films. Subsequently, gold (Au) and silver (Ag) nanoclusters were formed on the film surfaces using simple reduction techniques. Au- and Ag-doped TiO2 films showed a wider spectral range for photocatalysis and enhanced mechanical properties. The ability of the films to degrade methylene blue (a model organic dye) in simulated sunlight has been demonstrated using UV-visible spectroscopy. Reusability and mechanical integrity of the films after irradiation were also investigated.
