Abstract

The invention discloses a Fe-doped ZnO nano-film as well as a preparation method and application thereof. A Fe-doped ZnO nano-material is successfully prepared on a GPET transparent conductive flexible substrate through a hydrothermal method, the photocatalytic performance of the Fe-doped ZnO nano-material is researched. Zinc nitrate hexahydrate, hexamethylenetetramine and ferric nitrate nonahydrate are taken as main reactants, firstly ion sputtering is conducted on the surface of a flexible substrate GPET to obtain a very thin ZnO seed crystal layer; then Fe-doped ZnO precursor solutions withdifferent concentrations are prepared; and the flexible substrate is vertically put in a reaction solution, and a Fe-doped ZnO nano structure is grown by a hydrothermal method to obtain the Fe-ZnO / GPET nano composite material which can be used as a photocatalyst. The product obtained through the hydrothermal reaction has a special regular hexagonal nanorod-like structure, has a strong degradationeffect on a methylene blue solution, has a wide research prospect in the fields of environmental governance and the like, and is suitable for large-area production and application.

Description

【Technical field】

[0001] The invention belongs to the technical field of metal oxide semiconductor materials, and in particular relates to an Fe-doped ZnO nanometer film and a preparation method and application thereof. 【Background technique】

[0002] As an n-type semiconductor, zinc oxide (ZnO) is widely used in the photocatalytic degradation of organic dyes because of its wide bandgap of 3.37eV, high exciton binding energy of about 60meV, anisotropic growth and environmental protection. catalyst of light. However, ZnO inhibits the photocatalytic efficiency due to the rapid recombination of photogenerated electron-hole pairs. For nanomaterials, doping can significantly change its properties, because the number of atoms after doping is small and most of them are on the surface of nanomaterials.

[0003] At present, the synthesis methods of ZnO nanomaterials include evaporation method, sol-gel method, atomic layer deposition method, vapor phase deposition method, spray pyro...
