Abstract

The application discloses a preparation method and application of a FeOOH quantum dot modified amino-rich porous ultrathin graphite phase carbon nitride (g-C3N4) nanosheet high-efficiency photo-Fenton water purification material, and belongs to the technical field of functional nanomaterial preparation, solar energy utilization and environmental protection. The preparation method of the material is as follows: a commercial nitrogen-rich precursor (cyanamide, dicyanodiamide or melamine) and a high-molecular structure directing agent (CTAB, P123 and polyethylene glycol) are used as raw materials, uniformly mixed, directly calcined in air, and then subjected to chemical etching treatment to prepare an amino-functionalized porous ultrathin g-C3N4 material (AHUCN). Then, FeOOH quantum dots are loaded on the surface of the AHUCN material by using a coprecipitation method, so that a FeOOH@AHUCN photocatalytic material is obtained. The method is simple and easy to implement, and low in cost; the prepared material can be applied to photo-Fenton purification of antibiotic pollutants in water under sunlight, and has an important application prospect.
