Abstract

The invention discloses an amphiphilic porous hollow carbon microsphere, a preparation method thereof, applications of the amphiphilic porous hollow carbon microsphere as a carrier in enriching and loading of active molecules or a catalyst, and a method for separating and recovering the porous hollow carbon microsphere from a dispersion system by utilizing the amphipathy. The method comprises thefollowing steps of: dispersing microzyme in an aqueous solution of a cytoderm surface protectant; and then, carrying out carbonation treatment to obtain the amphiphilic porous hollow carbon microsphere. The prepared hollow carbon microsphere has a pore size capable of being controlled in the mesoporous and macroporous range as required, and can be suitable for the loading, the storage and the transmission of guest molecules in different sizes; by utilizing the characteristic of the amphiphilic porous hollow carbon microsphere capable of spontaneously transferring to a two-phase interface froma polar or non-polar dispersion system, the microsphere can be conveniently separated and recovered from a reaction mixing system. The easy and low-cost synthesis method and the special properties ofthe hollow carbon microsphere are favorable to the applications of the hollow carbon microsphere to the fields, such as energy storage, medicament transmission, artificial cells, catalytic carriers, and the like.

Description

technical field

[0001] The invention relates to an amphiphilic porous hollow carbon microsphere and its preparation method and application. Background technique

[0002] In recent years, due to their unique properties and great potential application value, hollow microspheres with well-ordered structure, especially hollow microspheres with porous spherical shells, have attracted extensive attention of many researchers. The porous spherical shell structure allows guest molecules such as dyes, drugs, phase-change materials, cells, and proteins to freely enter the inner cavity of the microspheres, thereby greatly improving the loading, storage, and transportation efficiency of these active molecules. Therefore, this porous and hollow structural feature will help the application of porous hollow microspheres in the fields of energy storage, drug delivery, artificial cells, and catalytic carriers.

[0003] At present, the methods for preparing porous hollow microspheres are main...
