| titleOfInvention | Defect-rich ultra-thin bismuth oxyiodide nano-sheet preparation method |
| abstract | The present invention discloses a defect-rich ultra-thin bismuth oxyiodide nano-sheet preparation method, which comprises: uniformly mixing a bismuth nitrate pentahydrate ethylene glycol solution and a potassium iodide ethylene glycol solution according to a volume ratio of 1:1; adding a small amount of an organic aldehyde reagent to make the organic aldehyde reagent concentration in the mixed solution be 0.2-1 g/L; transferring into to a hydrothermal reaction kettle, and carrying out a heat treatment for 12-24 h at a temperature of 150-180 DEG C; and after the hydrothermal reaction kettle is cooled to a room temperature, carrying out alcohol washing on the olive green product of the hydrothermal reaction kettle, carrying out water washing, and drying to obtain the product. According to the present invention, the viscosity of the ethylene glycol is high, the bismuth nitrate pentahydrate and the potassium iodide react in the high viscosity ethylene glycol system, and the grain growth is slow, such that the generation of the ultra-thin bismuth oxyiodide nano-sheets is easily achieved; and the organic aldehyde has the effects of the usual alcohol solvents and further normally has a certain reduction property, such that the [Bi2O2]<2+> unit on the surface is easily reduced through the organic aldehyde after the bismuth oxyiodide nano-sheets are subjected to ultra thinning so as to cause a lot of defects. |
