| titleOfInvention | A kind of nanometer titanium dioxide photocatalyst and preparation method thereof |
| abstract | The invention discloses a nano-titanium dioxide photocatalyst and a preparation method thereof. The method comprises the following steps: S1: mixing β-cyclodextrin and sodium hydroxide solution uniformly, and adding chloroacetic acid to obtain modified cyclodextrin; S2: Mix the modified cyclodextrin with nano-titanium dioxide, adjust the pH of the system with a phosphate solution, and add cyanamide, that is, modified titanium dioxide; S3: Mix the concentrated sulfuric acid potassium permanganate evenly, add water and hydrogen peroxide and mix evenly, that is It is graphene oxide; S4: composite graphene oxide and modified titanium dioxide, that is, modified photocatalyst; S5: immersed modified photocatalyst in hydrogen iodide solution, which is nano-titanium dioxide photocatalyst, using this process The prepared nano-titanium dioxide photocatalyst has good photocatalytic performance and adsorption, strong stability, avoids aggregation of nano-titanium dioxide, simple process, and green environmental protection. |
