Abstract
The present invention relates to complexed nanoparticle materials including metal sub-nanoparticles and chalcopyrite nano cores. The metal sub-nanoparticles are distributed on the surfaces of chalcopyrite nano cores. The complexed nanoparticle materials have improved light absorption property because the surface plasmon resonance of metal nanoparticle to effectively convert light into thermal energy. The complexed nanoparticle materials further include dispersants which are attached on the surface of the complexed nanoparticle materials. A solvent mixture with similar polarity can be separated by adding the complexed nanoparticle materials with dispersants, and then irradiating sunlight through a focusing component to the solvent mixture.
