• Bi2O3 and MIL101(Fe), respectively. The enhanced photocatalytic activity is attributed to the formation of a Z-scheme heterojunction between Bi2O3 and MIL101(Fe), which is conducive to the rapid separation of photogenerated carriers and the enhancement of photogenerated electron and hole redox capacity

• –organic frameworks; MIL101(Fe); photocatalysts; Z-scheme heterojunction; Introduction Tetracyclines, as the second most widely used antibiotic in the world, have been widely applied in clinics, aquaculture, and livestock due to its broad-spectrum antibacterial properties and low price [1][2

• , respectively [41]. In recent years, artificial Z-scheme heterojunction catalysts have generated extensive interest since its special electronic structure not only promotes separation of electron–hole pairs but also remains with high redox capacity [42]. Therefore, the photocatalytic activity of MIL101(Fe) can
