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.

用于能量转换和存储的分级功能纳米材料的构建

由于基于多层结构的耦合和协作的性能优势,分级功能纳米材料在新能源和环境领域具有重要的应用。应用的关键是中尺度结构的设计和控制,例如晶面结构,晶格取向,缺陷和位错。在这篇综述中,我们介绍了通过多相反应过程可控合成具有三维分层结构的新型半导体氧化物和碳基纳米复合材料。我们描述了几种典型的反应过程,例如气相火焰燃烧方法,气相沉积技术和固液界面反应过程,以研究流体流动,混合,传输和化学反应的性质。我们还通过结合实验和模拟方法研究了分层纳米材料的形成机理,结构演变和控制方法。这些精心设计和准备的分层功能材料可用于能量存储和转换领域。为新功能纳米复合材料的结构设计和性能控制提供了有价值的信息。
