Abstract:
我们测定了Ce_(0.6)Zr_(0.35)Y_(0.05)O_2和Pr_(0.6)Zr_(0.35)Y_(0.05)O_2两种固熔体的晶体结构,氧的储存以及Redox性能。XRD结果表明:Ce_(0.6)Zr_(0.35)Y_(0.05)O_2主要以立方的Ce_(0.75)Zr_(0.25)O_2结构形式存在,此外还有少量的ZrO_(1.87)。而Pr_(0.6)Zr_(0.35)Y_(0.05)O_2则主要以立方的Pr_(0.60)Zr_(0.40)O_2结构形式存在。这两种固熔体粒子都为纳米级,具有多孔和较大表面积的特征。将Y~(3+)掺杂到Ce_(0.6)Zr_(0.4)O_2或Pr_...
