Fe2O3 is iron(III) oxide or hematite, while Fe3O4 is a mixed oxide known as magnetite or iron(II,III) oxide. Difference Between Fe2O3 and Fe3O4 Table of Contents ADVERTISEMENTKey Differences Fe2O3 and Fe3O4 are both iron oxides but differ in their iron and oxygen content. Fe2...
According to the method for producing the immobilized-enzyme provided in the present invention, the enzyme can be easily collected and reused after the immobilization of enzymes on a ferric oxide (Fe_3O_4)-graphene oxide structure which is a magnetic substance. The reactivity, pH, and a ...
Spherical iron oxide powders with a mean diameter of 200 nm were obtained from Luoyang Tongrun Info Technology, Co., Ltd., China. All original chemicals are of analytical grade and used as receiving. Deionized (DI) water was used in all experiments for synthesis and washing. 2.2 Preparation ...
-derived 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF). HMF is composed of a hydroxyl and a carbonyl compound, both the hydroxyl and carbonyl groups can be oxidized in the oxidation process, which makes the selective oxidation to a single product of DFF ...
Magnetic hyperthermia is one of the most promising techniques for treating gynecological cancer, where magnetite (Fe3O4) is the most common nanomaterial used as a magnetic hyperthermia agent. Here, we demonstrate that optimal Fe3O4 nanorods (NRs) can act
The synthetic route toward SP-Fe3O4-C is illustrated in Fig.1a. First, polymer cubosomes with an ordered double primitive topology (DP-PCs) were prepared via self-assembly of polystyrene-block-poly(ethylene oxide) (PS241-b-PEO45) in solution following previously reported procedures (see detail...
A 1.0 g amount of PVDF and 0.8 g of Fe3O4 were placed in an oven at 80 °C for 1 h. Additionally, 1.0 g of PVDF was added to a mixed solution of 10 mL of DMF and acetone (7:3 v/v), placed on a magnetic stirrer at room temperature, and stirred for 10 h. Another part ...
However, there is a problem that the effective absorption bandwidth (EAB, the frequency bandwidth of reflection loss is less than −10 dB) of the X band is narrow. Increasing the EAB value of Fe3O4-carbon-based materials is of great significance for reducing electromagnetic pollution. Here...
Oxide is seldom used in the DSSC, due to poor electrical conductivity and low electro-catalytic activity for the reduction of I3− in the redox electrolyte. Whereas, as a typical layered transition metal oxide, Fe3O4 is a solid solution of FeO and Fe2O3. Owing to the difference in ion...
