Facile assembly of a hierarchical core@shell Fe3O4@CuMgAl-LDH (layered double hydroxide) magnetic nanocatalyst for the hydroxylation of phenol

The effects of manganese oxide octahedral molecular sieve chitosan microspheres on sludge bacterial community structures during sewage biological treatment

“…5b. We found two peaks centred at 710 and 724 eV indexed to Fe 2p 3/2 and Fe 2p 1/2 with a ratio of 61.1:38.9, which are consistent with the Fe(III) and Fe(II) oxidation states, respectively33.…”

Adsorption of Cd(II) by Mg–Al–CO3- and magnetic Fe3O4/Mg–Al–CO3-layered double hydroxides: Kinetic, isothermal, thermodynamic and mechanistic studies

“…To improve the efficiency of separation, magnetic separation technology (i.e., applying an external magnetic field to perform the separation) has attracted much attention [23][24][25]. As a result, introducing magnetic properties to the adsorbent has become a research hotspot, and many researchers have synthesized magnetic Fe 3 O 4 /LDHs to enhance the separation of adsorbents from aqueous solution after adsorption [26][27][28][29][30].…”

Fe3O4@SiO2 nanoparticles as a high-performance Fenton-like catalyst in a neutral environment

“…[8][9][10][11][12][13][14][15] Many studies have demonstrated that under sonication or irradiation, Fe3O4 nanoparticles (NPs) could decontaminate many organic pollutants. 16,17 Very recently, we showed that upon coating Fe3O4 NPs with a thin layer of carbon, Fe3O4 NPs catalyzed the Fenton-like reaction effectively without external energy supply.…”
