Coordination chemistry of metal–organic frameworks: Detection, adsorption, and photodegradation of tetracycline antibiotics and beyond

Modular Construction of an MIL-101(Fe)@MIL-100(Fe) Dual-Compartment Nanoreactor and Its Boosted Photocatalytic Activity toward Tetracycline

“…A large specific surface area of MOFs enriches TC and provides a broad platform for TC to contact the photocatalyst. Hence, the combination of adsorption and photocatalysis provides a semiconductor@MOF heterojunction with excellent abilities in the purification of low-concentration TC wastewater. ,,, Jin et al prepared the ZnIn 2 S 4 @PCN-224 heterojunction, where the TC removal rate reached 99.9% within 60 min, which was nearly 4.7 times than that of the single-component ZnIn 2 S 4 . Our group prepared the TiO 2 @UiO-66-NH 2 core–shell catalyst via the thermal solvent method, where the degradation rate of TC reached 75% within 2 h .…”

“…The overuse of TC causes excretion in its original form via urine and feces, which contaminates the underground and surface water bodies. Moreover, it accumulates in organisms, promoting microbes to develop resistance genes that threaten human life and health. − Therefore, efficient removal of TC from water is extremely urgent.…”

“…Therefore, the biological method only possesses a limited purification effect on high-concentration TC wastewater; however, it cannot achieve efficient purification of trace TC wastewater . In recent years, thanks to the large specific surface area, adjustable pore size, and simple synthesis method, metal–organic frameworks (MOFs) have exhibited a prominent impact on the adsorption of trace TC wastewater. , For example, the TC uptakes over NU-1000, UiO-66, and MOF-525 are 356, 145, and 807 mg/g at 25 °C and 2 h, respectively . However, the application of most MOFs in TC wastewater purification is limited due to their poor water stability and easy desorption of adsorbents .…”

“…6 Additionally, certain reported MOFs have displayed semiconductor characteristics. Although many MOFs have a large specific surface area, due to their wide band gap, electron−hole pairs are convenient to reassemble, making it difficult to balance both photocatalytic and adsorption effects, 2,3,11 for example, the TC removal rate of NH 2 -UiO-66 under visible light after 2 h only reaches 22%. 12 T h i s c o n t e n t i s Over the last several years, numerous studies have been conducted on the synthesis of semiconductor@MOF heterojunctions.…”

Photocatalytic degradation of tetracycline antibiotic over a flower-like S-doped BiOBr: Performance, mechanism insight and toxicity assessment

“…In particular, pharmaceutical and personal care products (PPCPs) have resulted in significant antibiotic discharges, posing a serious threat to the safety of aquatic ecosystems (Wang et al, 2018a) and human health (Rodriguez-Mozaz et al, 2015;Hena et al, 2021). Tetracycline antibiotics and their residues, as pseudo-persistent pollutants, have a wide range of use in drug synthesis, animal feeding, clinical application, and other fields (Scaria et al, 2021;Ahmadijokani et al, 2022;Biswal and Balasubramanian, 2022;Warner et al, 2022). The possible adverse effects on human beings and aquatic ecosystems have become a topic of great concern (Zhu et al, 2013).…”
