in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...

Iron oxide (Fe2O3) nanoparticles were synthesized by a simple approach using sodium borohydride (NaBH4) and Iron chloride hexahydrate (FeCl3.6H2O). Their physicochemical properties were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS). XRD pattern showed that the iron...

Maghemite (γ-Fe2O3) nanoparticles were obtained by coprecipitation of ferrous and ferric salts in an alkaline medium followed by oxidation; the nanoparticles were coated with poly(N,N-dimethylacrylamide) (PDMA) and characterized by transmission electron microscopy, attenuated total reflection (ATR) Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering, thermogravimetric and e...

Well-defined ferrocene-containing triblock copolymers were synthesized by atom transfer radical polymerization and self-assembled into highly ordered hexagonal arrays of cylinders via solvent annealing. The thin films were further used as a template and converted into highly ordered iron oxide nanoparticles (α-Fe2O3) by UV/ozonolysis and thermal pyrolysis.

Iron oxide nanoparticles (α- Fe2O3) were synthesized using an unconventional, eco-friendly technique utilizing a Hibiscus rosa sinensis flower (common name, China rose) extract as reducer and stabilizer agent. The microwave method was successfully used for the synthesis of iron nanoparticles. Various volume ratios chloride tetrahydrate to taken heated by oven different periods optimize nanopart...

The onset potential is an important parameter that affects the water oxidation performance of photoanodes. Herein, we investigated the behavior of the photocurrent onset potential of hematite (α-Fe2O3) photoanodes by incorporating Sn(4+) cations via external (surface overlayer) or self (underlying FTO substrate) doping. The α-Fe2O3/FTO photoanodes fabricated at both low (550 °C) and high (800 °...

Iron oxides are widely used as catalysts for photo-Fenton-like processes dye oxidation. In this study, we report on the synthesis of an α/γ-Fe2O3 mixed-phase catalyst with magnetic properties efficient separation. The was synthesized using glycine–nitrate precursors. samples were characterized scanning electron microscopy, X-ray diffraction spectroscopy (XRD), Raman shift spectroscopy, photoele...

Because of the diversification industries in developing cities, phenomenon simultaneous contamination various kinds pollutants is becoming common, and environmental process multi-contaminated mediums has attracted attention recent years. In this study, p-arsanilic acid (ASA), a kind organic arsenic feed additive that contains group chemical structure, used as typical contaminant to investigate ...

Selective adsorption and surface hydrolysis of [Fe(CN)6](3-) anions on α-Fe2O3 crystals was found to be a crucial process in the formation of a snowflake-like morphology, and the established mechanism is complementary to the classical theories of crystal growth.

Assorted common contaminants namely organic dyes and nitro compounds are generated by various industries have caused alarming problems for the environment humans. The development of effective newer methods to eliminate these is imperative. One way pollutants deploy sustainable heterogeneous catalyst systems. Accordingly, a novel efficient magnetic nanocomposite comprising graphitic carbon nitri...
