Abstract:
Not like the macroscopic building materials, the controllable assembly of blocks into superstructure has not been conquered in microscale, especially for the ordinary particles with shape defects and weak surface activities. Here, a facile route of assembling particles into superstructures utilizing Mo-polydopamine complex as the binder and curing agent is established. A side-by-side adsorption and growth mechanism in a water/ethanol system is derived, and the factors influencing the final structures are verified. This system is suitable to assemble superstructures from particles of different shapes such as nanospheres, nanocubes, nanorods, and hollow spheres in the range from 10 to 500 nm in size. And after high temperature and etching treatment, the generated MoO2/N/C frameworks with superpore structures derived from different blocks exhibit a high structural plasticity and potential application as multifunctional carriers for energy storage. Rather than the obtained system, our work assembles superstructures from various building blocks and explores more valuable complex cements for superstructures construction.
