Magnetic Fe3O4 based layered double hydroxides (LDHs) nanocomposites (Fe3O4/LDHs): recent review of progress in synthesis, properties and applications

Abstract

In view of the previous work on magnetic Fe 3 O 4 nanoparticles-based layered double hydroxides (magnetic Fe 3 O 4 /LDHs) as novel photocatalyst, research on this group of composites became one of the most attractive topics of nowadays. The magnetic Fe 3 O 4 /LDHs materials are often utilized for environmental remediation and photocatalysis. Hybrids of layered double hydroxides (LDHs) and Fe 3 O 4 MNPs are efficient nanocomposites due to their flexible properties and the excess of composition available for modification. So, critically reviews on the hybrid of the work magnetic Fe 3 O 4 /LDHs composite are the first report that efficient nanocomposites because of their flexible properties, energy and time used for separation, reduced consumption of additional materials can result in significant environmental and economic benefits. "The electrostatic interaction between the positively charged LDHs nanocomposites and negatively charged Fe 3 O 4 MNPs is adequate to make the formation of stable self-assembly of the two components". This review article discussed the magnetic Fe 3 O 4 /LDHs nanocomposites synthesis and applications in the photo catalysis, drug delivery and environmental remediation.

Release of a liver anticancer drug, sorafenib from its PVA/LDH- and PEG/LDH-coated iron oxide nanoparticles for drug delivery applications

“…The absorption bands at 1046 cm −1 and 947 cm −1 belong to the O–M–O lattice vibration (SO was intercalated into MLDH by co-precipitation and ion exchange method). It should be considered that bands' intensity has been reduced and shifted owing to interactions between LDHs and the synthesized nanoparticles 47 , 48 .…”

Halloysite nanotubes filled with salicylic acid and sodium diclofenac: effects of vacuum pumping on loading and release properties

“…The reason for their rapid diffusion has to be found in their wide variety of different and tunable features, including the morphology, size, interfacial chemistry [1][2][3][4][5][6][7]. Moreover, they are natural occurring building blocks that can be used as raw components for the design of new green and eco-sustainable materials [8][9][10][11][12][13]. Nowadays, the latter aspect appears to be the most important and attractive factor since it deals with some environmental needs which demand great efforts especially from researchers and technologists [14][15][16].…”

Photocatalytic Degradation of 2,4,6-Trichlorophenol by MgO–MgFe2O4 Derived from Layered Double Hydroxide Structures

“…The properties of an LDH will depend on its structural characteristics and will determine the applications that can be given to them. A characteristic that is determinant for the use of an LDH is its profile of evolution of phases by thermal treatment, which allows dehydration, deanionization, and dehydroxylation, with the subsequent formation of a variety of double and simple mixed metal oxides [8][9][10] Among the main applications that have been found to thermally decompose the products of LDHs is heterogeneous catalysis [11][12][13][14]. More specifically, heterogeneous catalysis assisted by irradiation of ultraviolet and visible light as an advanced process of oxidation of recalcitrant and/or persistent organic molecules has become of interest as a potential application of LDHs [15,16].…”
