2D BiOBr/MOFs composite for dye degradation under visible light

Shuai-ru Zhu  Meng-ke Wu  Lei Han  
【摘要】:MOFs nave generated a great dear of interest in recent years ror potential applications in gas storage,separation,sensor devices,biomedicine and catalysis.BiOBr,a novel 2 D layered ternary oxide semiconductor,has been found to have potential photocatalytic ability under visible-light illumination.Due to its low efficiency of light absorption,low adsorption capacity,and high recombination rate of photoinduced electron-hole pairs,the photocatalytic activity of pure BiOBr is limited.Hence,we report BiOBr/NH_2-MIL-125(Ti)and the in situ growth of CAU-17 on BiOBr composites.In the pollutants degradation experiment,The good synergy between MOFs and BiOBr was expected to play a crucial role in achieving the excellent photocatalytic degradation properties[1-5].Thus,this research is of considerable significance because it opens up extensive opportunities to the development of 2 D BiOBr/various MOFs composites for water treatment and other potential applications in the future.Now,a series of photocatalytic composites(such as BiOBr/MIL-101(Cr),BiOBr/MIL-53(Fe) and BiOBr/Pt-MOF-253,etc.) is ongoing.
