Ship-in-bottle synthesis in mesoporous silica and development of highly functionalized surface

有序介孔固体的孔道可以作为纳米反应器使用。这一点在具有较大比表面积的介孔二氧化硅表面的功能化中很明显，尽管它们的制备和分析还没有从这个角度进行。由于在纳米反应器中使用催化剂，中孔表面的功能化是不可避免的，我们开始研究中孔表面反应的最基本的方面：反应的顺序，控制进入孔/表面反应的相对扩散速度。虽然这种方法很简单，但我们可以从相同的反应物中探索各种各样的表面结构。结果表明，过渡金属络合物表面有多种不同的结构，在选择性氧化反应中表现出明显不同的催化作用。

The pores of ordered mesoporous solids could work as nanoreactor. This is evident in the functionalization of mesoporous silica surface with a large surface area, though their preparations and analyses have not been carried out in this standpoint. Since, in the use of catalysts in nanoreactors, functionalization of the mesopore surface is inevitable, we started investigating the most fundamental aspects of surface reactions on the mesopore surface: the order of reactions, controlling the relative rate of diffusion into the pores/surface reaction. Although this approach is simple, we can explore the wide variety of surface structures from the same reactants. We show that several different structures are obtained in transition metal complexes on the surface, which show considerably different catalyses in selective oxidation reactions.
