Hierarchical ultrathin ZSM-5 zeolite samples with controllable crystal growth directions were realized by designing bifunctional soft templates with different hydrophobic alkyl chain groups. MFI-type crystal growth along the a-c plane and stacking along the b-axis could be controlled to form nanowires of ZSM-5, which exhibited better catalytic activity for phenol hydroxylation than nanosheets of ZSM-5.
通过设计具有不同疏水烷基链基团的双功能软模板，实现了具有可控晶体生长方向的分级超薄ZSM-5沸石样品。可以控制沿a-c平面的MFI型晶体生长和沿b轴的堆积，以形成ZSM-5纳米线，其对苯酚羟基化的催化活性比ZSM-5纳米片更好。
