Z-scheme Bi4O5Br2/NH2-MIL-125(Ti) heterojunctions enable exceptional visible photocatalytic degradation of organic pollutant

One key strategy to enhance photocatalytic performance is to improve the transfer and separation efficiency of photogenerated carriers by building optimized heterojunctions. Herein, novel Bi4O5Br2/NH2-MIL-125(Ti) Z-scheme heterojunctions are fabricated and used as photocatalysts for organic pollutant photodegradation. The NH2-MIL-125(Ti) nanosheets are exfoliated via a self-developed alkali solution stripping approach and then uniformly decorated on Bi4O5Br2. The as-prepared Bi4O5Br2/NH2-MIL-125(Ti) presents more than 90
