Abstract

A precursor comprises the following components in parts by weight: 5 parts of ethylene glycol citrate; 1-2 parts of water-soluble cellulose; and 1-10 parts of metal nitrate. The method for preparing carbon nanomaterials is as follows: 1) taking materials in proportion, dissolving them in water and mixing them evenly, and concentrating to obtain a mixed solution; 2) putting the mixed solution obtained in step 1) into a reaction vessel, and heating the mixture under the condition of 250-400° C. The reaction was carried out for 1-10min to obtain carbon nanomaterials. The obtained carbon nanometer material can be used as an energy storage active material of an electrode sheet, and can be used to prepare a high-performance capacitor or a lithium ion battery.

Description

technical field

[0001] The invention relates to the field of nanomaterials, in particular to a precursor and a method and application for preparing carbon nanomaterials. Background technique

[0002] Due to their excellent chemical stability, remarkable electrical conductivity, and unique micro / nanostructure, carbon nanomaterials are considered as potential alternative materials in the fields of polymer industry, environmental treatment, heterogeneous catalysis, and advanced electronic devices. When carbon nanomaterials have a porous structure, high specific surface area, hybrid structure, and proper heteroatom doping, their energy storage performance becomes particularly prominent and competitive.

[0003] Currently, different methods, such as hydrothermal carbonization (HTC), template-assisted carbonization, electrochemical deposition, and powder carbonization, have been developed to synthesize different types of nanocarbon materials from various organic precursors. Howev...
