High loading on a porous support is important for preparing high-performance metal catalysts, but the increased loading often results in a loss of dispersion and limited mass transfer. We approached this problem by supporting a large amount of metal or metal oxide on a hierarchically porous zeolite. The supported catalyst formed an embedded network of nanowires along the zeolite mesopores. Although tightly filled in the mesopores, the catalyst was readily accessible through microporous windows at the encasing mesopore walls. Cobalt, nickel, and TiO2, supported in this manner, exhibited high catalytic performance in Fischer–Tropsch synthesis, benzene hydrogenation, and furfural-to-γ-valerolactone conversion, respectively.

可通过微孔窗进入的，分级沸石介孔网络中高负荷条件下负载的金属催化剂的限制
多孔载体上的高负载量对于制备高性能金属催化剂很重要，但是增加的负载量通常会导致分散性损失和有限的传质。我们通过在分层多孔沸石上负载大量金属或金属氧化物来解决此问题。负载型催化剂沿着沸石中孔形成了纳米线的嵌入式网络。尽管紧密地填充在中孔中，但是通过包裹在中孔壁上的微孔窗很容易获得催化剂。以这种方式负载的钴，镍和TiO 2分别在费托合成，苯加氢和糠醛向γ-戊内酯的转化中表现出较高的催化性能。
