Highlights

• Mesoscale structures of functional nanomaterials affect their properties directly.

• Mesoscale structures can be controlled by fluid flow, mixing, transport and chemical reaction.

• Hierarchical nanomaterials can be used in energy storage and conversion.

Abstract

Hierarchical functional nanomaterials have important applications in the fields of new energy and the environment because of performance advantages based on the coupling and collaboration of multi-level structures. The key to application is the design and control of the mesoscale structures, such as the crystal-facet structure, lattice orientation, defects, and dislocations. In this review, we present the controlled synthesis of novel semiconductor oxide and carbon-based nanocomposites with three-dimensional hierarchical structures by the multiphase-reaction process. We describe several typical reaction processes, such as the gas-phase flame-combustion method, the vapor-phase deposition technique, and the solid–liquid interface reaction process, to investigate the properties of fluid flow, mixing, transport, and chemical reaction. We also study the formation mechanism, structural evolution and control methods for hierarchical nanomaterials by using combined experimental and simulation methods. These well-designed and prepared hierarchical functional materials can be used in energy storage and conversion fields. Valuable information is provided for the structural design and performance control of new functional nanocomposites.
