The application belongs to the technical field of material chemistry and water treatment, and provides a CQD-MOF stable polysulfone hollow porous microsphere and preparation and application thereof. The CQD@UiO-66-NH2 is prepared by condensation synthesis, then the polysulfone and PVP are dissolved, CQD@UiO-66-NH2 is added and mixed, and then a coagulation bath is carried out to form CQD@UiO-66-NH2 / PSF composite hollow microspheres. The composite hollow microspheres not only have the inherent high specific surface area and a large number of active sites of UiO-66-NH2, but also show the advantageous properties of excellent photocatalytic capacity and low-density recyclable characteristics of CQD, and have excellent degradation efficiency on tetracycline and methylene blue, and have good industrial application prospect.

This invention belongs to the field of inorganic nanoparticle preparation technology, and relates to a ball milling modification method for bifunctionalized thin-layer hexagonal boron nitride: Hexagonal boron nitride powder, guanidine hydrochloride, and urea are continuously heated and stirred to obtain a homogeneous mixture of a eutectic solvent formed by guanidine hydrochloride and urea and the hexagonal boron nitride powder; this mixture is poured into a ball mill jar containing grinding balls and a liner, and a certain amount of ethanol and water are added as dispersants for high-energy ball milling; after the material is separated from the grinding balls, the milled material is vacuum filtered, dried, and the resulting powder is dispersed in water, then ultrasonicated, allowed to stand, vacuum filtered, and dried to obtain bifunctionalized thin-layer hexagonal boron nitride. This invention not only has the advantages of readily available raw materials and simple process, but also high efficiency, environmental friendliness, and low energy consumption. The hexagonal boron nitride obtained by this method has thinner layers, good biocompatibility, low relative density, and good thermal conductivity.
