Up to date we have developed several effective strategies to design and synthesize various porous nanostructures from MOFs. In this last stage of our JSPS project, we demonstrated some interesting chemical and physical properties of the obtained nanostructures.Hierarchical tubular-structured CoS2-MoS2/C as efficient electrocatalysts were fabricated through a unique metal-organic framework (MOF) mediated self-sacrificial templating. Core-shell structured MoO3@ZIF-67 nanorods were used both as a precursor and a sacrificial template to form the one-dimensional tubular heterostructure where vertically aligned two-dimensional CoS2-MoS2 nanosheets were formed on the MOF-derived carbon tube. Trace amounts of noble metals (Pd, Rh, and Ru) were successfully introduced to enhance the electrocatalytic property of the CoS2-MoS2/C nanocomposites.Overall, this MOF-mediated strategy can be extended to the rational design and synthesis of other hollow heterogeneous catalysts for scalable hydrogen generation.

到目前为止，我们已经开发了几种有效的策略来设计和合成各种多孔纳米结构的MOFs。在JSPS项目的最后阶段，我们展示了所获得的纳米结构的一些有趣的化学和物理性质。通过独特的金属有机框架（MOF）介导的自牺牲模板制备了作为高效电催化剂的分级管状结构的CoS 2-MoS 2/C。核-壳结构的MoO3@ZIF-67纳米棒既用作前体又用作牺牲模板以形成一维管状异质结构，其中在MOF衍生的碳管上形成垂直对齐的二维CoS 2-MoS 2纳米片。成功引入微量贵金属（Pd、Rh和Ru）来增强CoS 2-MoS 2/C纳米复合材料的电催化性能。总体而言，这种MOF介导的策略可以扩展到其他可扩展制氢的中空非均相催化剂的合理设计和合成。
