Construction of a novel Z-scheme V2O5/NH2-MIL-101(Fe) composite photocatalyst with enhanced photocatalytic degradation of tetracycline

The construction of Z-scheme systems is a valid strategy to effectively enhance photocatalytic property in the field of photocatalysis. In the present work, a novel Z-scheme V2O5/NH2-MIL-101(Fe) heterojunction photocatalyst was prepared via a simple one-pot solvothermal method for the first time. The phase structure, morphology and optical property of the as-prepared V2O5/NH2-MIL-101(Fe) composite were carried out by a series of characterizations. The photocatalytic property of V2O5/NH2-MIL-101(Fe) heterojunction photocatalyst was investigated by photodegrading tetracycline (TC) under ultraviolet-visible light irradiation. The systematic studies that the obtained V2O5/NH2-MIL-101(Fe) heterojunction photocatalyst possesses superior photocatalytic performance toward TC removal. Furthermore, a Z-scheme photocatalytic degradation mechanism for TC over V2O5/NH2-MIL-101(Fe) composites was proposed. The results show that Z-scheme V2O5/NH2-MIL-101(Fe) heterojunction photocatalyst has potential application in the treatment of TC wastewater. This research will broaden the studies of NH2-MIL-101(Fe)-based Z-scheme photocatalysts.
