Thermodynamic and kinetic properties of metal ions in aqueous solution
While it is evident that a metal ion in aqueous solution interacts electrostatically with water molecules and the anions present in the solution, it is equally apparent that often the metal ion chemically combines with varying numbers of ions or molecules to form complex species. This tendency towards coordination complexing is observed most often with the transition metals and results in a ser...
متن کاملMetal Hydrides: Transition Metal Hydride Complexes
Solid-state metal hydrides provide a safe and efficient way of storing hydrogen (Schlapbach 2002). They are commercialized for use in rechargeable batteries and developed for energy conversion devices such as fuel cells (see Hydrogen Metal Systems: Electrochemical Reactions). A great majority of metal hydrides derives from intermetallic compounds and alloys (see Hydrogen Metal Systems: Hydride ...
متن کاملkinetic and thermodynamic studies of zinc removal from a metal-plating wastewater using firouzkouh zeolite
introduction with the rapid development of industries such as metal plating facilities, mining, fertilizer producing industries, tanneries and paper industries heavy metals enriched wastewaters are directly or indirectly discharged into the environment. zinc is a trace element that is essential for human health. it is important for the physiological functions of living tissues and regulates man...
متن کاملMetal hydrides for lithium-ion batteries.
Classical electrodes for Li-ion technology operate via an insertion/de-insertion process. Recently, conversion electrodes have shown the capability of greater capacity, but have so far suffered from a marked hysteresis in voltage between charge and discharge, leading to poor energy efficiency and voltages. Here, we present the electrochemical reactivity of MgH(2) with Li that constitutes the fi...
متن کاملHydrogen-Mediated Metal Transport in Complex Metal Hydrides
Since this discovery, a number of studies have looked at improving the catalytic effects and understanding the role of additives in H2 cycling. However, the mechanism by which NaAlH4 is activated in the presence of a small amount of a transition metal is still not well understood. One of the principle questions is “How do the Al atoms migrate the long distances required during the hydrogenation...
