| titleOfInvention | A modified N,S-GQDs@CdS nanocatalyst and its preparation and application |
| abstract | The invention relates to a modified N,S-GQDs@CdS nano-catalyst and its preparation and application. The catalyst takes CdS as a core, grows N,S-GQDs on the surface, and connects the two through a covalent bond, The N,S-GQDs are graphene quantum dots doped with nitrogen and sulfur. The preparation method specifically includes the following steps: (a) dissolving citric acid and thiourea in water and dispersing them ultrasonically, then transferring them to a reactor for hydrothermal reaction, and then performing cooling, rotary evaporation and drying in sequence to obtain N,S-GQDs (b) get the N, S-GQDs obtained in step (a) and dissolve in water, then add cadmium acetate dihydrate, polyvinylpyrrolidone and thioacetamide to mix and ultrasonically disperse, and then transfer to the reactor to carry out hydrothermal reaction , followed by cooling, washing and drying in sequence to obtain N,S‑GQDs@CdS. Compared with the prior art, the photocatalyst of the present invention can expand the light absorption range and facilitate hole-electron separation, and can also improve the catalytic efficiency, and has good degradation ability to methylene blue under ultraviolet light conditions. |
