Abstract:

Carbon nanomaterials are a class of functional materials that provide a robust platform in the deve-lopment of energy storage, heterogeneous catalysis, high-performance compounding, biomedicine, and other fields. Therefore, the effective control of synthesis of carbon nanomaterials is of great significance to the deve-lopment of related fields. Layered double hydroxide with the precisely-controlled both type and content of host layer metal cations can form metal nanocatalysts with high dispersion and high stability in different types, densities and particle size distributions after roasting and reduction. The obtained metal nanocatalysts can be further applied to the efficient catalytic growth of various types of carbon nanomaterials. In addition, the factors such as reaction conditions and reactors also have an effect on LDH-based metal nanocatalysts-catalyzed growth of carbon nanomaterials. This article summarizes the research work in the field of LDH-based metal nanocatalysts preparing carbon nanomaterials from the aspects of the controllable preparation of catalysts, the structure regulation of carbon nanomaterials, and the application of carbon nanomaterials prepared by LDH-based catalysts, and clarifies that the controllable preparation of catalysts is the core means for the controlled synthesis of carbon nanomaterials, which points out the direction for the next step of LDH-based catalyst controlled synthesis of higher performance carbon nanomaterials. In addition, this article also combines the progress of scientific research in recent years in the fields of light, electricity, as well as photothermal catalysis, and looks forward to the research prospects of growing carbon nanomaterials based on new LDHs nanostructures.
