Depositing Cu2O of different morphology on chitosan nanoparticles by an electrochemical method

The chitosan nanoparticles were prepared with the least chemical productions by adding sodium sulfate. The cuprous oxide (Cu2O)/chitosan nanocomposites were prepared by electrochemical deposition of nanocrystalline Cu2O on chitosan nanoparticles. With the change of the reaction conditions, it was found that Cu2O nanoparticles could be leafage-like or big spherical particles coated on the surface of chitosan nanoparticles. The composition of the resulting Cu2O/chitosan composites was confirmed by using SEM images, XRD pattern, and XPS spectrum. The chemical interaction between Cu2O and chitosan nanoparticles was probed into by FTIR spectrum. The Cu2O/chitosan nanocomposites make it possible of seeking materials that can degrade pollutants with minimal energy and the least reagent under biocompatible and environmentally friendly conditions.
