Growth of Cu2O Nanocubes from Seeds in MicrowellsPublic Deposited
This project focused on the growth of Cu2O nanocubes in microwells from nanoparticle “seeds.” The seeds were first formed by the reduction of copper sulfate with ascorbic acid in the presence of the surfactant poly(ethylene glycol) (PEG). Upon reaction within the microwell, the seed solution formed a larger single crystal. By varying the amount of precursor seed particles available in the reaction, nanocubes of different sizes were formed. The surfactant was removed from the surface of the nanocubes using ethanol. The nanocubes were characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM).
