无锂熔融碳酸盐中STEP电解质的稳定化
Stabilization of STEP electrolyses in lithium-free molten carbonates
摘要:
本通讯报道了在无锂熔融碳酸盐中的有效电解。利用太阳能热能来驱动高效电解的过程被称为太阳能热电化学过程(STEP)。不含锂的熔融碳酸盐,例如使用铱阳极的碳酸钠-钾低共熔物,或使用镍阳极的碳酸钙-钠-钾低共熔物,可以为STEP电解提供有效的介质。这种电解可用于STEP碳捕获,以及生产包括STEP燃料、铁和水泥在内的主食。
英文摘要:
This communication reports on effective electrolyses in lithium-free molten carbonates. Processes that utilize solar thermal energy to drive efficient electrolyses are termed Solar Thermal Electrochemical Processes (STEP). Lithium-free molten carbonates, such as a sodium-potassium carbonate eutectic using an iridium anode, or a calcium-sodium-potassium carbonate eutectic using a nickel anode, can provide an effective medium for STEP electrolyses. Such electrolyses are useful in STEP carbon capture, and the production of staples including STEP fuel, iron, and cement.
