The invention relates to the technical field of photocatalytic degradation, and discloses a SnS2 - g - C3N4 heterojunction photocatalytic degradation material, comprising the following formula raw materials and components: honeycomb Ag -doped g - C3N4 , carbon nanotubes, tin tetrachloride, thioglycolic acid, cetyl trimethyl ammonium bromide. The SnS 2 ‑g‑C 3 N 4 heterojunction photocatalytic degradation material has honeycomb Ag-doped g‑C 3 N 4 , which has abundant pore structure and huge specific surface area. Ag doping makes g‑C 3 N The light absorption edge of 4 is red-shifted, which enhances the responsiveness and utilization of photocatalysts to light energy, and nano-SnS 2 hollow microspheres-modified carbon nanotubes are deposited on Ag-doped g-C 3 N 4 with abundant pore structure and huge pore structure. On the specific surface, a heterojunction structure is formed, and the carbon nanotubes form a three-dimensional conductive network between SnS 2 and Ag-doped g‑C 3 N 4 , which promotes the separation of photogenerated electrons and holes under the synergistic effect, resulting in a large number of Photogenerated electrons and holes generate highly active superoxide radicals and hydroxyl radicals, and carry out the degradation process of organic pollutants. |
