Construction of S-scheme MIL-101(Fe)/Bi2MoO6 heterostructures for enhanced catalytic activities towards tetracycline hydrochloride photodegradation and nitrogen photofixation
This study reported the construction and photocatalytic applications of S-scheme MIL-101(Fe)/Bi2MoO6 heterostructures via a solvothermal reaction. The morphologies and microstructures of these heterostructures were comprehensively studied. The heterostructures exhibited enhanced photocatalytic activities towards tetracycline hydrochloride (TCH) photodegradation and nitrogen photofixation compared with the corresponding single components. Approximately 96.2% of TCH can be removed using the MIL-101(Fe)/Bi2MoO6(2:1) heterostructure at the optimized component ratio. Moreover, the resultant MIL-101(Fe)/Bi2MoO6(2:1) heterostructure demonstrated considerably enhanced photocatalytic activity towards nitrogen photofixation, and the produced NH4+ concentration reached up to (0.836 ± 0.057) mg·L−1 without the addition of any sacrificial agents. The improved photocatalytic activities of MIL-101(Fe)/Bi2MoO6 heterostructures can be attributed to the enhanced surface areas, effective charge separation and the development of S-scheme heterostructures between Bi2MoO6 and MIL-101(Fe). This research thus offers helpful insight into the fabrication of S-scheme systems for photocatalytic applications.
