Herein, we report on the synthesis of Ce_0.5Zr_0.5−xTi_xO₂ oxygen storage materials prepared via a solution combustion method. Ce_0.5Zr_0.4Ti_0.1O₂ showed an outstanding oxygen storage capacity (1310 μmol-O per g) at 200 °C compared to conventional κ-Ce₂Zr₂O₈ (650 μmol-O per g) due to its cation ordering and the formation of weakly bound oxygen atoms induced by Ti substitution.

钛取代引起的阳离子有序铈锆锆的储氧能力增强†

在本文中，我们报告了通过溶液燃烧法制备的Ce _0.5 Zr _{0.5− x} Ti _x O ₂储氧材料的合成。的Ce _0.5 Zr的_0.4钛_0.1 ø ₂表明在200℃下的杰出的储氧能力（1310微摩尔-O每g）相对于传统的的κ-CE ₂的Zr ₂ ö ₈（650微摩尔-O每g）由于其阳离子排序Ti取代引起的弱结合氧原子的形成。
