Abstract

Abstract : Chloride both promotes the transformation of Cu nanocluster self-assembled architectures from one-dimensional (1D) to 2D, and facilitates the transformation of Cu2− x S nanocrystals from nanorods to nanosheets. Abstract : Self-assembly and crystallization are two common methods to control the morphologies of nanomaterials, which have many similarities. In this work, chloride is used to direct the self-assembly process of Cu nanoclusters and the subsequent growth of Cu2− x S nanocrystals. Meaningfully, chloride both promotes the transformation of Cu nanocluster self-assembled architectures from one-dimensional (1D) to 2D, and facilitates the transformation of Cu2− x S nanocrystals from nanorods to nanosheets. Such an influence is attributed to the selective adsorption of chloride ions on the specific facets of nanoclusters and nanocrystals, which alters the inter-nanocluster weak interactions during self-assembly and suppresses the activity of Cu2− x S facets during nanocrystal growth. The current results indicate that the method used to direct the morphologies of nanocrystals is extendable to control the tendency of nanocluster self-assembly.
