Description

technical field [0001] The invention belongs to the technical field of preparation of supported photocatalytic materials, and in particular relates to a method for preparing a stainless steel mesh-supported bismuth oxide nanosheet photocatalyst by a solvothermal method. Background technique [0002] TiO 2 Semiconductor materials such as semiconductors can absorb ultraviolet rays in sunlight. When the energy of the radiation is greater than or equal to the forbidden band width of the semiconductor, the electrons in the semiconductor are excited to jump from the valence band to the conduction band, while the holes stay in the valence band, making the electrons The separated electrons and holes are reductive and oxidative respectively, and the electrons can reduce H 2 O produces H 2 , the holes can oxidize H 2 O becomes O 2 . In the presence of organic matter, holes can oxidize organic matter to CO 2 and H 2 O, etc., are widely used in the photocatalytic degradation of o...
