Abstract

Here, we report a synthetic, polymer-mediated method for the self-assembly of zinc/copper hydroxide carbonate superstructures including 3D hierarchical sunflower-like, urchin-like, alga-like, and rotiform-like zinc hydroxide carbonate (ZHC) microstructures, and hierarchical copper hydroxide carbonate (CHC) microspheres with radiating nanoplates and nanorods. As a capping agent, poly(vinylpyrrolidone) (PVP) was found to play an important role in directing the growth and self-assembly of such unique structures. T he crystal structure of the products and the resulting hierarchical superstructure morphology, as controlled by the molecular weight and concentration of PVP, were systematically investigated. A possible growth mechanism for the formation of hierarchical superstructures with different morphologies is also proposed.
