The invention discloses a method for preparing silver-doped soft carbon-carbon nitride-TiO 2 composite material from waste cotton. The waste cotton is used as a raw material, it is calcined into soft carbon under nitrogen atmosphere, and Ag is embedded in the soft carbon. In the micropores of carbon, it is prevented from growing and deforming. Using the method of quaternary ammonium salt intercalation-assisted grinding, the g-C 3 N 4 particles were ground into few-layer g-C 3 N 4 nanosheets, and ultrasonically oscillated in the isopropanol solution of polyvinylpyrrolidone, and the particles were peeled off. Monolayer g ‑ C3N4 nanosheets. The monolayer g ‑ C3N4 nanosheets and isopropyl titanate were then mixed-milled in a vibratory hammer mill, and finally hydrothermally loaded together with silver quantum dot-doped soft carbon to improve Photocatalytic properties of soft carbon, silver, nanographitic carbon nitride and titanium dioxide. |
