Abstract

Iron-doped manganese oxides were synthesized using a co-precipitation method and thermodynamically characterized to demonstrate their potential as a thermochemical energy storage medium. Thermochemical energy storage, via chemical bonds that employ reversible redox reactions, is a promising approach to tackle solar thermal energy storage. Hysteresis loops observed confirm that the pore network consisted of mesopores that were not filled with pore condensate, and the narrow loop indicates a narrow size distribution. Barrett-Joyner-Halenda (BJH) studies of all the synthesized materials showed that they have a high mesoporous and specific area, essential for supplying reduced diffusion channels over the Mn oxides, Good conductivity through electron transfer, with the presence of active sites allow the study thermochemical approaches. The BJH studies showed the material MnOFe2 (2.5:1) to have a higher pore area, which is effective in the adsorption process of the material.
热储能用掺杂铁锰氧化物的合成与表征
采用共沉淀法合成了铁掺杂锰氧化物,并对其进行了热力学表征,证明了其作为热化学储能介质的潜力。热化学储能,通过化学键采用可逆氧化还原反应,是解决太阳能热能储存的一个很有前途的方法。观察到的滞回线证实了孔隙网络由中孔组成,未被孔隙凝析液填充,窄的滞回线表明孔径分布较窄。Barrett-Joyner-Halenda (BJH)对所有合成材料的研究表明,它们具有高介孔和比面积,这对于提供Mn氧化物上的还原扩散通道至关重要,通过电子转移具有良好的导电性,活性位点的存在允许热化学方法的研究。BJH研究表明,MnOFe2(2.5:1)材料具有更高的孔面积,这在材料的吸附过程中是有效的。
