采用硝酸盐-柠檬酸燃烧法合成了单一电解质 Ce0. 8Gd0. 1Tm0. 1O2-α,再将 Ce0. 8Gd0. 1Tm0. 1O2-α粉和二元硫酸盐( K_2SO4、Li_2SO4) 混合,重量比为 7 ∶ 3,制备得到 Ce0. 8Gd0. 1Tm0. 1O2-α-KLi SO4复合电解质。用 X 射线衍射( XRD) 测定了 Ce0. 8Gd0. 1Tm0. 1O2-α和 Ce0. 8Gd0. 1Tm0. 1O2-α- KLi SO4的晶体结构。用电化学工作站测量Ce0. 8Gd0. 1Tm0. 1O2-α-KLi SO4在 500~800 ℃和不同氧分压范围内的交流阻抗谱。结果表明: 在相同的测试温度条件下,Tm3+和 Gd3+双掺杂 Ce O2电解质电导率高于单掺杂 Ce O2电解质,是单一电解质的 2 倍。
