Highly efficient degradation of azo dyes by palladium/hydroxyapatite/Fe3O4 nanocatalyst

SPION/β-cyclodextrin core–shell nanostructures for oil spill remediation and organic pollutant removal from waste water

“…It is a suitable candidate for photodegradation under visible light condition. Fe 3 O 4 based nanomaterials are promising for wastewater treatment and biological applications because of their low cost, strong adsorption capacity, bio-compatibility, easy separation, photocatalytic ability and enhanced stability [13][14][15]. Among Iron oxide nanoparticles use of superparamagnetic nanoparticles is increasing because in contrast to other magnetic materials they do not show spontaneous magnetic moments and do not agglomerate due to magnetic dipole-dipole interactions.…”

Facile synthesis of Fe3O4/SiO2/molecularly imprinted hydroxyapatite nanocomposite and its enhanced photocatalytic degradation of target contaminant

“…Magnetic separation provides a simple and effective method for removing and recycling magnetic particles from the treated water by external magnetic field. The accommodation of magnetic nanocrystallites into HAP matrix has been reported by several researchers and used as a high-performance heterogeneous catalyst [4][5][6]. The core-shell Fe 3 O 4 /HAP nanoparticles have been successfully prepared and used as photocatalysts for photocatalytic degradation of organics in our previous report [7,8].…”

“…FeCl 3 Á6H 2 O, NaAc, Ca(NO 3 ) 2 Á4H 2 O, simazine, atrazine, pirimicarb and prometryn were of analytical grade and obtained from Shanghai Chemical Reagent Co. Tetraethoxysilane (TEOS), triethyl phosphite (P(C 2 H 5 O) 3 ) and Ti(O-n Bu) 4 were purchased from Sigma Chem. Co. and used as received.…”

Green synthesis of copper nanoparticles for the efficient removal (degradation) of dye from aqueous phase

“…and exhibit significant environmental toxicity to all living organisms and contribute to eutrophication (Safavi and Momeni 2012). These possess a threat to our ecosystem and water bodies.…”
