The ultimate control of the interfaces of nanocomposite materials is essential to tailor and improve their physical/chemical properties in applications such as catalysis, or energy storage or production. Fabrication and co-assembly of a variety of nanostructured colloids is a promising way to design the interface of materials in nano-scale toward high functionality. In this study, we demonstrate a synthesis of colloids of nanocluster-sized (~ 2 nm) cobalt and nickel hydroxides and their assembly into microparticles that present hetero-nanointerfaces. Electrochemical properties were investigated to elucidate the effect of the hetero-nanointerface. Microparticles with hetero nanostructures composed of cobalt and nickel hydroxide nanoclusters revealed improved mass specific capacity (91.4 mAh/g) compared with respective microparticles with homo-nanointerface (cobalt hydroxide; 15.8 mAh/g: nickel hydroxide; 64.4 mAh/g). Further investigation suggests that the introduced hetero-nanointerface leads to lower charge transfer resistance and to improved electrochemical properties. The synthetic concept demonstrated here is expected to create unique hetero-nanointerfaces for various materials with wide-range of chemical composition towards improved and novel functionalities. |
