Summary

This joint research effort between Purdue University and the Forest Service's Forest Products Laboratory investigated the use of cellulose nanofibers (CNF) for engineering a variety of hybrid inorganic-biological materials. Functional films with potential applications in water decontamination were produced with the incorporation of silver, gold and titanium dioxice nanoparticles with CNF. Composite films of titanium dioxide-CNF were shown to be strongly photocatalytically active in ultraviolet light, and subsequent modification with gold and silver nanoclusters were shown to enhance photocatalytic efficiency in visible light. Additionally, gold and silver modifications improved the reusability of the titanium dioxie-CNF films by minimizing mechanical deterioration.
