Flagella-Templated Process to Noble Metal Nanoparticles/TiO2 Composite Films and Their Photocatalytic Activity
In this work, flagella are used to control over the growth and assembly of Au and Ag nanoparticles, and a stable dispersion of flagella/metal nanoparticle is successfully obtained. A composite film with a TiO2/Au(Ag)/TiO2 sandwich structure is prepared by means of a dip-coating method where a dialyzed TiO2 solution and flagella stabilized Au and Ag nanoparticles are used as raw materials. TEM and UV-visible spectroscopy characterizations reveal that the sandwich structures play a role in stabilizing metal nanoparticles in the composite films and visible light photocatalytic activity is attributed to the existence of Au and Ag nanoparticles.
