Abstract

The invention discloses a construction unit head-body-tail three-section amphiphilic molecule of a hydrophilic and hydrophobic molecule self-assembled micelle embedded with an aromatic amide fragment.According to the three-section amphiphilic molecule, the aromatic amide oligomer fragment is embedded in a conventional hydrophilic and hydrophobic molecule. The invention also discloses a preparation method of forming a water-phase ultra-uniform round micelle assembly by the construction unit. The invention also discloses a preparation method of a supramolecular photocatalytic assembly, and thesupramolecular photocatalytic assembly is prepared by carrying out a reaction on the prepared hydrophilic and hydrophobic molecule self-assembled micelle embedded with the aromatic amide fragment witha catalyst in a water-phase sacrificial reagent. The hydrophilic and hydrophobic molecule self-assembled micelle embedded with the aromatic amide fragment has extremely high chemical and structural stability in water, is ultra-uniform and monodisperse and has controllable particle size. The supramolecular photocatalytic assembly provided by the invention is suitable for producing hydrogen by reducing water phase protons under atmospheric atmosphere at normal temperature and normal pressure and selectively reducing carbon dioxide to prepare CO and CH4 under normal temperature and normal pressure in a carbon dioxide atmosphere, and does not contain noble metals.

Description

technical field [0001] The invention belongs to the technical field of organic visible light catalytic materials, and in particular relates to a preparation method of self-assembled micelles of hydrophilic and hydrophobic molecules embedded with aramid fragments and a supramolecular photocatalytic assembly. Background technique [0002] The sun continuously provides thermal energy to the earth. It is the main source of light and heat on the earth. So far, it has delivered about 120,000 terawatts of electricity, which is expected to be 4,000 times higher than the electricity required by human civilization in 2050. How to effectively use and store these energies is a topic that human beings have been constantly exploring and researching. [0003] Storage of solar energy into chemical fuels via carbon-neutral strategies, e.g., splitting water into H 2 and O 2 Or convert carbon dioxide into valuable organic compounds, offering a potential solution to the fossil fuel crisis.
