Chitosan/palladium {CTS/Pd}(n) composite multilayer film was assembled based on layer-by-layer self-assembly technique and in-situ photo-chemical reduction reaction, in which the CTS plays the role of a photo-reduction agent and an assembly reagent. Transmission electron microscopy (TEM) shows that spherical Pd nanoparticles with diameter of 20 nm are well-dispersed in the composite multilayer films, and the size of Pd nanoparticles increased gradually with the extension of illumination time. Besides, the {CTS/Pd}(n) composite multilayer film exhibits linear, uniform and regular layer-by-layer growth. Furthermore, the {CTS/Pd}(n) composite multilayer film presents an excellent catalytic properties for oxygen reduction, and it has potential application in energy, chemical synthesis and biological processes.
