Method for preparing fullerene nano micron material loaded with transition metal and product of fullerene nano micron material

Abstract

The invention relates to a method preparing a fullerene nano micron material loaded with transition metal and a product of the fullerene nano micron material. The fullerene nano micron material refers to fullerene nano micron fiber (a fullerene nano micron crystal whisker and a fullerene nano micron tube) and a fullerene nano micron wafer. The method comprises a direct liquid-liquid interface loading method and a capillary adsorption method. The direct liquid-liquid interface loading method comprises steps of grinding a fullerene matter till the fullerene matter has metal luster, dissolving the fullerene matter in a good organic solvent so that the solution is a saturated solution, irradiating the saturated solution to a colloidal solution by using natural daylight or visible light in a container, mixing the colloidal solution and a certain amount of poor solvent containing a transition metal compound of certain concentration evenly, placing the mixture to a constant temperature incubator, standing, crystallizing and separating out the fullerene nano micron material loaded with the transition metal. The capillary adsorption method comprises that the transition metal compound is absorbed to the fullerene nano micron tube through a capillary principle. The method is simple, easy to implement, good in repetitiveness and applied to environmental protection fields such as fuel cell electrodes, catalysts, catalyst carriers, low dimensional semiconductors, functional polymer composite materials and valuable metal recycling in waste solvents.

Description

technical field [0001] The invention relates to the field of modification of fullerene-based nano-micron materials, in particular to a preparation method and a product thereof of fullerene-based nano-micron materials loaded with transition metals. Background technique [0002] Low-Winner micron-like carbon materials are ideal systems for studying the size and latitude effects of physical properties such as electron transport behavior, optical properties, and mechanical properties. Playing an important role, in order to realize its application expansion and functional diversification, the modification of low-dimensional nano-carbon structure materials has become the frontier and hot spot in the field of nano-micro-material science. [0003] Since the discovery of fullerene C by Kroto et al. in 1985 60 For a long time, fullerenes have unique physical and chemical properties due to their highly symmetric, spherically delocalized π-electron conjugated systems. The singular pho...

Problems solved by technology

The nanofibers synthesized by this method have single crystal structure, high aspect ratio and high purity (99.9%), however, the problem of this method is the preparation of fullerene C 60 、C 70 The nanotubes have a long growth period (more than one week), and the reproducibility is poor, so it is difficult to prepare on a large scale

Although there have been reports in the literature on the preparation of transition metal-loaded fullerene-like nano-micro-materials, the preparation methods reported so far have long growth cycles and poor repeatability, making it difficult to achieve large-scale preparation.
