Abstract

The invention relates to a method for preparing graphitized nano carbon, which relates to a method for preparing the nano carbon. The method solves the problems of low yield, low purity and uncontrollable shape in the prior art for preparing the graphitized nano carbon. The method comprises: coordination of carbon sources and metallic ions; complex curing; heat treatment; and activation treatment, so as to obtain the graphitized nano carbon. The graphitized nano carbon prepared by the method has high yield, high purity and controllable shape. The method is simple, easy to operate, and suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of nanometer carbon. Background technique [0002] Carbon materials combine some special properties of metals, ceramics and polymer materials, and play an important role in human civilization and scientific and technological progress with their unique properties and rich forms. Carbon material science began in the 1950s and has a history of more than 50 years. The discovery of fullerenes in 1985 and carbon nanotubes in 1991 opened up a new field of vision for the research of carbon materials science, and triggered an upsurge in the research of carbon nanomaterials. Numerous studies have focused on the preparation of these two carbon materials, Functionalization and property studies. Almost at the same time, some nano-carbons with novel structures have attracted the attention of some researchers due to their special morphology and singular properties, such as: polyhedral graphite particles in carbon ash p...
