Observable removal of pharmaceutical residues by highly porous photoactive cellulose acetate@MIL-MOF film

Synthesis and Characterization of Slow-Release Fertilizer Hydrogel Based on Hydroxy Propyl Methyl Cellulose, Polyvinyl Alcohol, Glycerol and Blended Paper

“…Cellulose is mainly found in high amount in different plant sources where it is cheap, abundantly available and biodegradable [ 19 ]. A lot of effort has been made to replace synthetic polymers with cellulose derivatives, which are used in controlled release for drugs [ 20 , 21 , 22 ], removal of pharmaceutical pollutants in waste water [ 23 , 24 ], dye removal in waste water [ 25 , 26 ] and agrochemicals after crosslinking [ 27 ]. Hydroxy propyl methyl cellulose (HPMC) is an odourless, tasteless, white to slightly off white fibrous or granular free flowing powder.…”

Low temperature curable titanium-based sols for visible light photocatalytic coatings for glass and polymeric substrates

“…The total dye removal results from the contribution of adsorption and photocatalysis processes. Considering previously published research studies for the microporous crystalline MIL-125-NH 2 MOF, 63,65,66 the NH 2 BDC ligand of the hybrid coatings seems to play a crucial role in both processes. On one side, the functional amino and carboxylate groups of the ligand and its core phenyl ring can favor specific electrostatic, hydrogen bonding and π–π interactions with the dye, promoting its marked adsorption into the metal–organic coating.…”

“…A similar behavior has been observed in the powdered samples of the crystalline MIL-125-NH 2 MOF (comprised by Ti-oxo clusters and NH 2 BDC ligands) in which the best catalytic performance occurs at mild pH values, while lowering the pH worsens the results. 63 However, in a basic media, no ligand leaching was observed, so the adsorption of the dye is noteworthily increased and as occurred in Ti-SG@450 the excess of the strongly adsorbed dye might explain the slight photocatalytic performance decay.…”

Recent advances in metal–organic frameworks and their composites for the phototherapy of skin wounds

“…Due to the unstable coordination bonds, MOFs can be degraded into small molecules and discharged out of the body. 62 Benefiting from these characteristics, MOF-based materials contribute to a wide range of applications in the removal of pesticides from wastewater, 63,64 the removal of pharmaceutical residues, 65–67 catalysis, 31 luminescence, 68 gas capture, storage and separation, 69,70 sensing, 71 solar energy capture, 72 energy storage, 70 electron and ion conduction and so on. In particular, the application of MOFs in the biomedical field has attracted extensive attention, mainly reflected in drug delivery, 73 biomimetic enzymes, 74 bioimaging, 75 cancer therapy, 76 antibacterial therapy, 77 and biomarker detection 78 (Table 1).…”
