Progress in preparation and application of carbon nanotube composites based on MOFs

Abstract

Carbon nanotubes(CNTs), as an important discovery in the research of nanomaterials, have become a research hotspot in the field of carbon materials since their birth. With its unique porous structure, metal-organic frameworks (MOFs) has been developed into one of the frontiers of research in recent years. With the continuous development of materials science in recent years, the research on composite technology of materials with different functional characteristics has become one of the main methods to solve key problems in the field of materials applications.CNTs and MOFs are two very important types of nanomaterials in the current material field. Combining the high electrical conductivity of CNTs with the high specific surface area and rich pore distribution characteristics of MOFs through composite technology is an inevitable trend for future research and application in the field of materials. In this paper, the main composite forms and preparation methods of MOFs and CNTs in recent years were reviewed, and the latest research progress of composites in the fields of supercapacitors, lithium battery electrodes, catalysis, adsorption, etc. was summarized. The synergistic improvement of the performance of the two materials was discussed and analyzed, and it was pointed out that the composite of CNTs and MOFs materials and the growth and distribution of CNTs have a high degree of randomness, and further control of them is the focus of future technical research.
