| 摘要: 采用溶剂热法，将不同物质的量的Y3+离子掺入金属有机框架UiO-67的次级结构单元（SBUs），得到具有Zr（Ⅳ）-O及Y（Ⅲ）-O混合次级结构单元的双金属有机框架Y/Zr-UiO-67。以此金属有机框架结构作为模板通过两步煅烧法制备介孔钇掺杂氧化锆。结果表明，这种金属有机框架结构衍生的氧化钇-氧化锆固溶体有高的比表面积和氧离子电导率。 |

| Abstract: Different amounts of Y3+ ions have been incorporated into the secondary building units (SBUs) of UiO-67 frameworks during solvothermal crystallization. The SBUs containing integral Zr(Ⅳ)-O and Y(Ⅲ)-O clusters are formed in this bimetallic Y/Zr-UiO-67. Mesoporous yttria doped zirconia is synthesized by two-step calcination treatment using the bimetallic MOFs as a template. This kind of MOFs derived solid solutions has a high BET surface and enhanced oxygen ion conductivity. |
