Abstract

The invention belongs to the technical field of advanced nanocomposite materials, and in particular relates to a mesoporous / macroporous composite carbon material with a multi-level ordered structure and a preparation method thereof. In the present invention, the colloidal crystal of silica mold is used as the hard template, the block copolymer surfactant of the polyoxyethylene segment is used as the soft template, and the phenolic resol resin is used as the carbon source. Synthesis of mesoporous / macroporous composite carbon materials with hierarchical channels. The material not only has interconnected ordered macropores but also short-range ordered mesoporous walls. In addition, this type of material has an optical band gap produced by a colloidal crystal structure, and the band gap wavelength is continuously adjustable. The material has broad application prospects in optical waveguides, sensors, and catalyst carriers. The method of the invention is simple, the raw material is easy to obtain, and is suitable for scale-up production.

Description

technical field

[0001] The invention belongs to the technical field of advanced nanocomposite materials, and in particular relates to a multi-level ordered mesoporous / macroporous composite carbon material and a preparation method thereof. technical background

[0002] In recent years, mesoporous carbon materials have broad application prospects in catalyst supports, supercapacitor electrodes, and fuel cells due to their superior properties such as the electrical conductivity of carbon materials and the high specific surface area of ​​mesoporous materials. The synthesis of traditional mesoporous carbon materials is usually obtained by nanocasting. This method first synthesizes mesoporous silica materials with a certain structure, and then fills the pores of mesoporous silica materials with organic molecules. As a carbon precursor, the organic matter was then carbonized and the silica template was further removed to obtain a mesoporous carbon material replica with a channel st...
