Two series of Fe2O3/TiO2 samples were prepared via impregnation and photodeposition methods. The effect of preparation method on the properties and performance of Fe2O3/TiO2 for photocatalytic degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) under UV light irradiation was examined. The Fe2O3/TiO2 nanocomposites prepared by impregnation showed lower activity than the unmodified TiO2, mainly...

Wang). ntributed equally Abstract Mesoporous Fe2O3 spherical particles with amorphous or crystalline structure were prepared at different temperatures using aerosol spray pyrolysis. The crystalline Fe2O3 (C-Fe2O3) anodes pyrolysized at 800 1C show better electrochemical performance than the amorphous Fe...

The development and utilization of magnetic nanoadsorption materials with large adsorption capacity easy separation are the research hotspot nowadays. In this study, nanosheet-assembled maghemite (γ-Fe2O3) microspheres were successfully synthesized by an environmental friendly, quick, simple method, for enhanced Sb(III) removal from aqueous solution. Scanning electron microscopy (SEM), X-ray di...

Nanocrystalline Fe2O3 thin films are deposited directly on the conduct substrates by pulsed laser deposition as anode materials for lithium-ion batteries. We demonstrate the well-designed Fe2O3 film electrodes are capable of excellent high-rate performance (510 mAh g- 1 at high current density of 15,000 mA g- 1) and superior cycling stability (905 mAh g- 1 at 100 mA g- 1 after 200 cycles), whic...

In order to create Fe2O3 and Fe2O3·H2O nanoparticles, various polymers were used as dispersing agents, and the resulting effects on the dispersibility and nanoparticulation of the iron oxides were evaluated. It was revealed that not only the solution viscosity but also the molecular length of the polymers and the surface tension of the particles affected the dispersibility of Fe2O3 and Fe2O3·H2...

Ancient Jian wares are famous for their lustrous black glaze that exhibits unique colored patterns. Some striking examples include the brownish colored "Hare's Fur" (HF) strips and the silvery "Oil Spot" (OS) patterns. Herein, we investigated the glaze surface of HF and OS samples using a variety of characterization methods. Contrary to the commonly accepted theory, we identified the presence o...
