| titleOfInvention | Bismuth oxybromide ternary heterostructure photocatalyst and preparation method and application thereof |
| abstract | The invention discloses a preparation method of a bismuth oxybromide ternary heterostructure photocatalyst. Bismuth nitrate pentahydrate, potassium bromide, graphite-phase carbon nitride and silver nitrate are used as raw materials, the prepared graphite-phase carbon nitride and silver bromide are compounded with bismuth oxybromide to realize modification, and the bismuth oxybromide ternary heterostructure photocatalyst is prepared by a one-step solvothermal method. Compared with pure bismuth oxybromide, the modified bismuth oxybromide prepared by the invention has smaller forbidden band width and higher visible light absorption effect. The smaller forbidden band width reduces the transmission distance of the photoproduction electron holes, improves the separation efficiency of the photoproduction electron holes, reduces the recombination rate, has higher light absorption effect, improves the photon utilization rate, improves the electron hole pair generation rate, and greatly improves the photocatalytic activity under visible light. The method has the advantages of low cost and convenient operation. The organic pollutant can be degraded by using the organic pollutant-degrading agent under visible light, and the organic pollutant-degrading agent has important practical value in environmental purification. |
