Macroions with moderate charge density and size between 1 nm to 10 nm are capable to self-assemble in solution, forming single-layer, hollow, spherical structures. These structures are called "blackberry structures", where the dominant driving force is the counterion-mediated interaction. What's more, the different types of the charged macroions are able to recognize themselves and self-assemble separately.

520 $a Macroions with moderate charge density and size between 1 nm to 10 nm are capable to self-assemble in solution, forming single-layer, hollow, spherical structures.

What's more, the different types of the charged macroions are able to recognize themselves and self-assemble separately.
520 $a On the other hand, as a promising carbon-free Water Oxidation Catalysts (WOCs) based on abundant metals, the sandwich-like cobalt-containing polyoxometalates (POMs), with formula Na10[Co4(H2O)2 (PW9O34)2], has been extensively studied. As a nano-sized charged ion, it is interesting to study its self-assembly behaviors in solution and the connections with catalytic performance. Here the solution behavior of the Co-containing POM was investigated. In this research, Laser Light Scattering (LLS), Isothermal Titration Calorimetry (ITC), Ultraviolet-Visible Light Spectrum (UV-Vis), X-Ray Diffraction (XRD) were used to investigate the counterions effect on the self-assembly process of this WOC. Using Ru(BPY) 3 (BPY: 2,2`-bipyridine, counterion: Cl-), an important component presented in water splitting system, as the counterion, it could self-assemble into hollow spherical structures with hydrodynamic radius ranging from 30 nm to 50 nm in aqueous solution, depending on the amount of Ru(BPY) 33+. Moreover, the effect of NaPi (Sodium Phosphate) buffer was studied by comparing with DI water. Overall, this study was aimed to provide more understanding of Co-containing POMs water splitting process.
