摘要/Abstract

摘要： 利用固相反应法和溶胶凝胶法在不同制备参数下制备了载氧体YBaCo₄O_7+○δ(Y114相)，利用XRD检测了样品的物相组成，使用热重分析仪研究了制备参数对Y114相中低温条件下氧储存能力的影响.结果表明:以固相反应法制备的Y114相样品的中低温氧储存能力强于溶胶凝胶法;二次煅烧20h样品的中低温氧储存能力更强;以固相反应法制备，在1150℃二次煅烧20h、炉冷冷却样品的非化学计量氧δ值为0.89;以溶胶凝胶法制备，在1050℃下二次煅烧20h、空冷冷却样品的δ值为0.83.

Abstract: A series of YBaCo₄O_{7+ ○δ○} oxygen carriers were synthesized by solid state reaction method and sol-gel method with different preparation parameters. The phase composition of the samples were analyzed by X-ray diffraction. The effects of preparation parameters on the oxygen storage capacity of Y114 phase at medium and low temperature were investigated by means of thermogravimetry. The experimental results show that the oxygen storage capacity of Y114 phase prepared by the solid state reaction method is higher than that of the one prepared by sol-gel method and the Y114 phase calcined for 20h has a better performance. The δ (nonstoichiometric oxygen) of Y114 phase is 0.89， where the sample is synthesized by the solid state reaction method， calcined at 1150℃ for 20h and furnace cooling， while the δ becomes 0.83 where it is synthesized by the sol-gel method， calcined at 1050℃ for 20h and cooled in air.

Key words: preparation parameters, Y114 phase oxygen carriers, phase composition, oxygen storage capacity, nonstoichiometry oxygen
