Abstract

The invention discloses a method for preparing micron materials by adopting surfactant-induced self-assembly metalloporphyrin, and belongs to the field of micron material preparation. The preparation steps of the present invention are as follows: (1) dispose aqueous solutions of anionic and cationic surfactants with different concentrations; (2) carry out the aqueous solution of metalloporphyrin with positive / negative charge and the aqueous solution of cationic / anionic surfactants in (1). Mixing, the control solution temperature is 5-90 ℃; (3) will hold the mixed solution of the metalloporphyrin aqueous solution or metalloporphyrin aqueous solution of negative / positive charge and the anion / cationic surfactant aqueous solution in (1), control system The temperature is 5-90°C, and then added to the system (2) at one time; stirring for 5min-24h. In the present invention, the morphology and details of the microstructure are further regulated by adding anionic and cationic surfactants in the mixing process of oppositely charged porphyrins. The material with micron snowflake structure has clear branch structure, which is more conducive to the loading and dispersion of metal particles.

Description

technical field [0001] The invention belongs to the field of preparation of micron materials, and in particular relates to a method for preparing micron materials by adopting surfactant-induced self-assembly metalloporphyrin. Background technique [0002] Ionic self-assembly is the use of two oppositely charged porphyrins (building blocks) to drive assembly through electrostatic interaction to prepare micro and nanostructures. Through ionic self-assembly technology, metal macrocyclic compounds can be assembled to obtain micro- and nano-materials with different morphologies, such as nanorods, nanofibers, four-leaf clover structures, nanospheres, nanosheets, etc. In most ionic self-assembly processes, the morphology of the assembled porphyrin is mainly adjusted by adjusting the pH value of the reaction system, the synthesis temperature, and changing the metal of the porphyrin. The prior art lacks control over the details of micron materials, which is not conducive to the fine...
