Active site regulated Z-scheme MIL-101(Fe)/Bi2WO6/Fe(iii) with the synergy of hydrogen peroxide and visible-light-driven photo-Fenton degradation of organic contaminants

The band structure analysis shows that BWO and MIL-101(Fe) is typical type-II scheme, which provokes that the photogenerated carriers will transfer from a more positive position to a more negative position. The Z-scheme heterojunction is proposed.
