Growth inhibition ofMicrocystic aeruginosaby metal–organic frameworks: effect of variety, metal ion and organic ligand

Abstract

MOFs have been applied in the inactivation of Microcystic aeruginosa. The algal suppression by MOFs depends on the presence of different metal ions and organic ligands.

Metal–organic-framework-based photocatalysts for microorganism inactivation: a review

“…82 In the last few decades, 316 pieces of literature have been reported concerning photocatalytic hours when the concentration of Cu-MOF-74 was 1 mg L −1 . 83 However, when the Cu-MOF-74 dosage exceeded 5 mg L −1 , the same inhibitory effect can be achieved within 2 hours. 84 The mechanism for inhibiting algal growth can be attributed to the presence of ˙OH and intracellular ROSs, with the released Cu 2+ and cell aggregation involved to some extent.…”

“…Fan et al (2018) evaluated the growth inhibition rate among five kinds of MOFs (Cu-MOF-74, Zn-MOF-74, ZIF-8, Ag/AgCl@ZIF-8, and MIL-125(Ti)) on M. aeruginosa , with Cu-MOF-74 performing the best, which showed an inhibition rate of 400% after 120 hours when the concentration of Cu-MOF-74 was 1 mg L −1 . 83 However, when the Cu-MOF-74 dosage exceeded 5 mg L −1 , the same inhibitory effect can be achieved within 2 hours. 84 The mechanism for inhibiting algal growth can be attributed to the presence of ˙OH and intracellular ROSs, with the released Cu 2+ and cell aggregation involved to some extent.…”

Coordination Polymers Constructed from an Adaptable Pyridine-Dicarboxylic Acid Linker: Assembly, Diversity of Structures, and Catalysis

“…Coordination polymers (CPs) are currently recognized as highly auspicious functional compounds owing to their captivating structural features, unique properties, and extensive diversity of applications in gas separation and storage, − sensing, − bioactive materials, − catalysis, − and many other areas. − The properties of CPs are governed by their structural and topological characteristics, as well as types of linkers and metal nodes. − Although the synthesis of coordination polymers can be tuned toward explicit structural and topological types, − a full control of the outcome of self-assembly reactions remains challenging because many factors can have an influence on the crystallization of CPs, namely, connectivity of linkers, , coordination preferences of metal ions, , presence of coligands, as well as reaction parameters (solvents, temperatures, pH values). − …”

“… 23 − 27 The properties of CPs are governed by their structural and topological characteristics, as well as types of linkers and metal nodes. 28 − 30 Although the synthesis of coordination polymers can be tuned toward explicit structural and topological types, 31 − 33 a full control of the outcome of self-assembly reactions remains challenging because many factors can have an influence on the crystallization of CPs, namely, connectivity of linkers, 34 , 35 coordination preferences of metal ions, 36 , 37 presence of coligands, as well as reaction parameters (solvents, temperatures, pH values). 38 − 42 …”

Inactivation of harmful algal bloom by an environmentally friendly photocatalyst under photo-Fenton-like degradation process

“…In our previous study (Fazli et al, 2021a(Fazli et al, , 2022, we studied the photo-Fentonlike degradation efficiency of different types of water contaminants in the presence of Fe3O4,Fe2.5Co0.3Zn0.2O4,Fe2.5Co0.3Zn0.2O4/CuCr-LDH composites. Moreover, from the previous studies, we knew that the materials containing Zn 2+ and Cr 3+ have an appropriate influence on the deactivation of microorganisms (Fan et al, 2018). Therefore, these efficient photo-Fenton catalysts were used to deactivate green algal cells as the biological water pollutants in the current work.…”
