With iron (hydr)oxide minerals (goethite, hematite, lepidocrocite, and magnetite) and with siderite, the e-values for CCl4 dehalogenation were remarkably similar (-29 +/- 3 per thousand). Because this value matches well with the theoretical estimates for the cleavage of an aliphatic C-Cl bond...
The oxide specimens were reduced in streams of pure hydrogen or carbon monoxide at temperatures between 700° and 1,200°C. The reduction was followed by measuring the sample weight during the reaction. Reduction rates were studied at system pressures of 1 and 2 at. The samples reduced step ...
This study intends to determine the adsorption efficiency of an iron oxide sorbent immobilised on naturally derived carbon foam for the removal of organic dye from an aqueous solution19. The effects of varying the iron content of the sorbent, contact time, dye concentrations, and sorbent dosage we...
To evaluate the role this oxide film plays in the reduction of chlorinated methanes, carbon tetrachloride (CCl ) degradation by Fe was studied under the influence of various anions, ligands, and initial CCl concentrations ([ P] ). Over the range of conditions examined in these batch ...
Pressure is measured using the equation of state of Pt. The sample completely transformed into the Py-FeO2Hx phase. The top panel is an integrated pattern from the 2D unrolled x-ray diffraction pattern at the bottom. The wavelength of the x-rays is 0.4066 Å. The strong diffraction ...
Hydrogenation of carbon dioxide was carried out over reduced Fe 3 O 4 catalyst. Effect of reduction temperature of the catalyst, reaction temperature, space velocity, and component of feed gas were examined on the catalyst. From various experiments, the proper conditions for the hydrogenation of ca...
Despite the fact that carbon dioxide is an abundant atmospheric gas with profound environmental implications, there is little information on the reaction of carbon dioxide at the adsorbed water-oxide interface. In this study, the chemistry of carbon dioxide at the adsorbed water-iron oxide interface...
the prepared iron oxide HGs are modified to offer important merits: (i) high specific surface area for available active sites; (ii) hierarchical porosity for short diffusion pathways; (iii) control of Fe2+/Fe3+ redox system for high electrocatalytic activity; and (iv) defective carbon formati...
This treatment also led to an increase in the interaction strength between the iron (III) oxide particles and the carbon support. It is shown that the transition from iron (III) oxide to iron sulfide proceeded through two intermediate phases, viz. an oxidic high-spin Fe2+-phase and FeS2. ...
To evaluate the role this oxide film plays in the reduction of chlorinated methanes, carbon tetrachloride (CCl4) degradation by Fe0 was studied under the influence of various anions, ligands, and initial CCl4 concentrations ([P]o). Over the range of conditions examined in these batch ...
