Description

technical field [0001] The invention belongs to the technical field of inorganic nanomaterials, in particular to a sea urchin-shaped three-dimensional Fe 3 o 4 / SnO 2 Nanorod arrays and their synthesis methods and applications. Background technique [0002] The use of adsorbents to adsorb organic pollutants and heavy metal ions and the use of semiconductor-based photocatalytic materials for photocatalytic degradation of organic pollutants are currently the most studied technologies. However, when it is applied in the sewage treatment process, the characteristics of difficult separation and recovery greatly restrict its wide application. The magnetic separation technology of photocatalysts is an ideal solution. [0003] Tin dioxide as a wide bandgap (E g =3.6eV) semiconductor materials, widely used in gas sensing, lithium-ion batteries, catalysis, adsorption and other fields. Due to the excellent photoelectric characteristics, chemical stability and non-toxicity of tin ...
