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...
rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to form a compound ‘iron oxide’. This iron oxide is rust. The process of rusting can be represented by the following word equation : ...
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...
PROBLEM TO BE SOLVED: To provide a lithium iron complex oxide for positive electrode active substance, capable of constituting a lithium secondary cell which has a large active material discharging capacity and is good in so called, cycling property able to maintain the capacity in spite of repeat...
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...
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 ...
