| titleOfInvention | Tin nanoparticle modified composite photocatalytic material with oxygen vacancy stannic oxide nanosheets and preparation method thereof |
| abstract | The invention discloses a tin nanoparticle modified tri-tin tetroxide nanosheet composite photocatalytic material with oxygen vacancies, which is prepared by carrying out in-situ reduction on nano-flake tri-tin tetroxide synthesized by a hydrothermal method in a hydrogen atmosphere on the basis of the nano-flake tri-tin tetroxide synthesized by the hydrothermal method, so as to obtain tri-tin tetroxide with oxygen vacancies, and modifying metallic tin to form a Schottky junction on the surface of the tri-tin tetroxide. The diameter of the stannic oxide nanosheet is 300-500nm, and the thickness is about 20 nm; the tin nanoparticles have a diameter of 50-200 nm. The photocatalytic material disclosed by the invention combines the properties of the Schottky junction and the oxygen vacancy, on one hand, the high-quality conductivity of metal and the metal/semiconductor Schottky junction promote the separation and transmission of carriers; on the other hand, oxygen vacancies can capture photo-generated charges and widen the photoresponse range by reducing the band gap of the semiconductor. The photocatalyst disclosed by the invention has high activity on oxidative degradation of organic pollutants under visible light, and the preparation method is simple, low in cost and wide in industrial application prospect. |
