摘要: X-ray diffraction and kinetic measurements show that the rate of oxidation of magnetite crystals smaller than about 0.2 to γ-Fe 2 O 3 is controlled by the diffusion of iron cations. A model of the mechanism is successful in describing the kinetics of the process....

A series of Fe2O3–CeO2 composite catalysts were synthesized by coprecipitation and characterized by X-ray diffraction (XRD), BET surface area measurement, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). Their catalytic activities in CO oxidation were also tested. The Fe2O3–CeO...
High-temperature static oxidation, the material is mainly formed on the surface of the oxide Fe2O3 and a small amount of Fe3O4, the internal structure of porous oxide layer, the interface with the substrate with relatively straight, evenly distributed in the material's surface ...
Development of Fe2O3-CeO2-TiO2/γ-Al2O3 as catalyst for catalytic wet air oxidation of methyl orange azo dye under room condition In order to develop a catalyst with high activity and stability for catalytic wet air oxidation (CWAO) process at room temperature and atmospheric pressure... L...
Oxidation, mixed oxidation–sulfidation and hot corrosion of ductile iron aluminide Fe3Al with Cr addition have been examined at temperatures of 605°C and 800°C. It is observed that Fe3Al–5Cr specimen tested at 605°C a small amount of island-like Fe2O3 was formed on the specimen surfa...
