[Abstract]:In this paper, the preparation and properties of nano-heterostructure photocatalysts are introduced. In the first chapter, the research status of nanoscale heterostructure materials is summarized, and the current research progress on wastewater treatment is summarized. The structure, morphology, magnetic properties and photocatalytic properties of Fe3O4 nanoparticles / FeWO4 nanowires were prepared by a simple one-step hydrothermal method. In Chapter 3, Fe3O4 polyhedrons were prepared by two-phase hydrothermal method. Then the Fe3O4 and WO3 were synthesized by hydrothermal synthesis, and the 緯 -Fe _ 2O _ 3 / WO _ 30.5H _ 2O heterostructure was prepared. The effects of different reaction conditions on the structure and morphology of the product were discussed, and the photocatalytic activity of the product was studied. Cu2O nanospheres with smooth surface were prepared by reflux method, and then sea urchin Cu2O/CuO nanoscale heterostructures were obtained by self-oxidation method. The oxidation time affected the morphology and composition of the products, and the composite products had a larger specific surface area. The adsorption and degradation characteristics of methyl orange dyes by Cu2O/CuO were investigated.
