| titleOfInvention | Preparation method and application of La-doped microspherical BiOBr-graphene composite material |
| abstract | The invention relates to the technical field of water pollution treatment, and discloses a La-doped microspherical BiOBr-graphene composite material, a BiOBr crystal is used as a common photocatalytic material, a Bi6s and O2p hybrid orbit increase a valence band space, reduce a copy ratio of a photo-generated electron-hole pair, enhance the separation of an electron/hole pair, the dispersibility of a Br energy band energy level, shorten the forbidden bandwidth, reduce the recombination of carriers, increase the specific surface area of a microspherical shape, have a similar ionic radius of rare earth elements La and Bi, have excellent modification performance, doping makes a conduction band potential negatively move, the specific surface area of carboxylated oxidized graphene is large, various oxygen-containing functional groups are provided to play a role of a surfactant, so that the catalytic material is easier to compound, the problem of ion agglomeration of BiOBr in a reaction is solved, and a good dispersion effect can be achieved in an aqueous solution, is a catalyst which is worthy of development and research and is suitable for water pollution treatment. |
