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

In view of the previous work on magnetic Fe3O4 nanoparticles-based layered double hydroxides (magnetic Fe3O4/LDHs) as novel photocatalyst, research on this group of composites became one of the most attractive topics of nowadays. The magnetic Fe3O4/LDHs materials are often utilized for environmental remediation and photocatalysis. Hybrids of layered double hydroxides (LDHs) and Fe3O4 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 Fe3O4/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 Fe3O4 MNPs is adequate to make the formation of stable self-assembly of the two components. This review article discussed the magnetic Fe3O4/LDHs nanocomposites synthesis and applications in the photo catalysis, drug delivery and environmental remediation.
