Bi2O2SiO3/Bi2O3Preparation method of BiOBr heterogeneous composite light material |
| abstract |
The invention discloses a Bi 2 O 2 SiO 3 /Bi 2 O 3 A preparation method of a BiOBr heterogeneous composite material. Bismuth nitrate is used as bismuth source, tetraethoxysilane is used as silicon source, sodium orthophosphate, sodium dodecyl sulfate, polyethylene glycol and the like are added to promote the formation of the required crystalline phase, and a precursor is prepared to prepare the Bi 2 O 2 SiO 3 /Bi 2 O 3 a/BiOBr heterogeneous composite material. The method has the advantages of simple process equipment, short period and low cost, and the obtained composite material powder has high photocatalytic performance. |
