Zinc oxide based materials are commonly used for the final desulfurization of synthesis gas in Fischer-Tropsch based XTL processes. Although the ZnO sulfidation reaction has been widely studied, little is known about the transformation at the crystal scale, its detailed mechanism and kinetics. A model ZnO material with well-determined characteristics (particle size and shape) has been synthesiz...
Introduction: A primary goal of meteoritics is to determine the physical and chemical environments in the early solar system that led to the properties of planets and other solid bodies. Since metal is highly reac-tive in oxidizing and sulfidizing atmospheres, it and its corrosion scales can record the composition and conditions of any alteration fluid that interacted with it. Metal-troilite-ox...
With the proliferation of use wireless communication technologies, lightweight, easily fabricated electromagnetic wave (EMW) absorbers are in great demand for commercial and stealth applications. In this paper, well-defined Cu2O microcubes were successfully converted into S-doped Cu2-xSe micro-cubic boxes at room temperature by a template-directed situ selenization/sulfidation reaction. The obt...
