| titleOfInvention | Ag-containing water surface floating3PO4And carboxylated g-C3N4Preparation method of hydrogel photocatalytic film |
| abstract | The invention discloses a water surface floating Ag-containing water 3 PO 4 And carboxylated g-C 3 N 4 A preparation method of a hydrogel photocatalytic film. First on g-C 3 N 4 Chemical oxidation is carried out to generate hydroxyl and carboxyl on the basal plane of the catalyst, in order to further improve g-C 3 N 4 Carboxyl content of the surface, g-C after chemical oxidation 3 N 4 Reaction with chloroacetic acid to give carboxylated g-C 3 N 4 . Carboxylation of g-C 3 N 4 Fully dispersing in water, adding silver nitrate to make silver ion fully adsorbed to carboxylation g-C 3 N 4 Surface, then adding excess soluble phosphate, carboxylating g-C 3 N 4 Surface generation of Ag 3 PO 4 Nanoparticles. Then adding soluble carbonate and sodium alginate into the system and fully dissolving to obtain a membrane casting solution, scraping the membrane casting solution into a membrane and soaking the membrane casting solution into a mixed aqueous solution of dilute hydrochloric acid and soluble calcium salt for fully reacting, wherein the hydrochloric acid reacts with the soluble carbonate to generate carbon dioxide bubbles, and simultaneously calcium ions are crosslinked to generate calcium alginate hydrogel, so that the carbon dioxide bubbles are sealed in the hydrogel to obtain the water-surface-floating Ag-containing hydrogel 3 PO 4 And carboxylated g-C 3 N 4 The hydrogel photocatalytic film of (1). |
