Embodiment 1

[0017] A Fe-Doped Double Pentagonal Pillar Morphology of Nano-TiO 2 The preparation method of the photocatalyst includes the following steps: ① Dissolve 6g of tetrabutyl titanate in 30mL of absolute ethanol, then add 20mL of oleylamine and 100mg of PVP, and stir to obtain liquid A; ② Mix 51mg of ferric nitrate nonahydrate and 150mg of EDTA- 2Na and 25mL DMF were mixed uniformly to obtain B solution; 3. B was added dropwise to A solution, stirred evenly, and then transferred to a hydrothermal reaction kettle, hydrothermally reacted at 200°C for 16h, filtered, washed and dried to obtain Fe mixed solution. Heteromorphic TiO with double pentagonal pillars 2 catalyst of light.

Abstract

The invention provides a Fe-doped nano-TiO 2 Application of photocatalyst in the degradation of p-nitrophenol. By using oleylamine, PVP and EDTA‑2Na in proportion as dispersants and morphology modifiers, combined with absolute ethanol and DMF as reaction solvents, Fe-doped double pentagonal pyramids with high-index crystal faces exposed on the surface were prepared. Nano-TiO with columnar morphology 2 Photocatalyst, the average particle size is 10nm, which greatly improves the TiO 2 The catalytic activity of the photocatalyst, and the degradation of p-nitrophenol under sunlight shows good catalytic activity, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of organic pollutant degradation, in particular to a Fe-doped nano-TiO 2 Application of photocatalysts in the degradation of p-nitrophenol. Background technique [0002] p-Nitrophenol is included in the list of 68 pollutants under priority control in my country's water environment, and it is also a key control object in the 129 priority control pollutants of the US Environmental Protection Agency (EPA). p-Nitrophenol is easy to attack the human body's hematopoietic cells, nervous system, liver, and kidneys, inactivating human cells and causing neurasthenia. High concentrations of p-nitrophenol are acutely toxic, which can easily lead to the death of animals and plants; low concentrations of p-nitrophenol are chronically toxic, and long-term exposure will make people feel sick, dizzy, anemia, and nervous center disorders. At high temperatures, p-nitrophenol can volatilize into a toxic gas that irritates the...
