我们证明了通过还原剂的气相渗透使用具有不同孔径的双螺旋介孔二氧化硅（KIT-6）的介孔Pt副本的简易合成。通过控制互补的孔径，可以选择性地将Pt存款到Ia（3）的一侧孔中而不是硬的双连续结构中，从而形成具有相对大的中孔（超过10 nm）的中孔Pt复制品。
We demonstrate facile synthesis of mesoporous Pt replicas using double gyroid mesoporous silica (KIT-6) with different pore diameters via vapor infiltration of a reducing agent. Through controlling the complementary pore size, it becomes possible to selectively deposit Pt into one side pore of the Ia (3) over bard bicontinuous structure, thereby forming a mesoporous Pt replica with relatively large mesopores (over 10 nm).
