Microwave heating of waste electric arc furnace dust (EAFD) for the purpose its remediation has been studied extensively. However, these studies considered EAFD as a bulk material without addressing either relative response individual constituents or specific interactions with magnetic fields an electromagnetic wave. In this work, we present study contribution wave components to using separated...

In this study, the performance of ZnFe2O4-Fe2O3 heterostructure was tested for photocurrent generation via photoelectrochemical activity under irradiation. Additionally, effect photoanode on structural, optical properties, and charge kinetic behavior photoelectrode investigated. A combination nanostructures exhibited an enhanced ability light absorption compared to that pristine Fe2O3 ZnFe2O4 s...

Zn, K, and Cu effects on the structure and surface area and on the reduction, carburization, and catalytic behavior of Fe–Zn and Fe oxides used as precursors to Fischer–Tropsch synthesis (FTS) catalysts, were examined using X-ray diffraction, kinetic studies of their reactions with H2 or CO, and FTS reaction rate measurements. Fe2O3 precursors initially reduce to Fe3O4 and then to metallic Fe (...
