| titleOfInvention | Method for preparing bismuth oxychloride/bismuth oxyiodide composite ultrathin nanosheet by ion exchange method |
| abstract | The invention discloses a method for preparing a bismuth oxychloride/bismuth oxyiodide composite ultrathin nanosheet by an ion exchange method, which comprises the steps of dissolving bismuth nitrate pentahydrate and polyvinylpyrrolidone in an ethylene glycol solution, stirring at room temperature until the bismuth nitrate pentahydrate and the polyvinylpyrrolidone are completely dissolved, adding a saturated sodium chloride solution into the solution, continuously stirring to obtain a white turbid solution, transferring the white turbid solution into a hydrothermal reaction kettle to react at 140-180 ℃, performing vacuum drying at 60 ℃ to obtain a product of the bismuth oxychloride ultrathin nanosheet, dispersing the bismuth oxychloride ultrathin nanosheet into a saturated potassium iodide solution, and stirring at 25-50 ℃ for 3-12 hours to obtain a target product of the bismuth oxychloride/bismuth oxyiodide composite ultrathin nanosheet. The method is simple and easy to operate and good in repeatability, the synthesized bismuth oxychloride/bismuth oxyiodide composite ultrathin nanosheet has an ultrathin two-dimensional structure, the specific surface area is large, the band gap of the bismuth oxychloride/bismuth oxyiodide composite ultrathin nanosheet is appropriate, and the photoresponse range is wide, so that the method has a good application prospect in the related fields of optics, electricity, thermodynamics and the like. |
