A one-step method to synthesize small size cup-like hollow ZSM-5 single crystals is reported in this paper. Characterization methods show that the product has a typical ZSM-5 structure and most crystals are uniform, mono dispersed crystal shells with distinct hollow structure. The average size of a single crystal is about 350 nm. Every cup-like hollow ZSM-5 crystal can act as a microreactor in the reaction, and the ZSM-5 based catalyst POM-MOF-ZSM-5 (polyoxometalates (POM), metal-organic frameworks (MOF)) shows excellent oxidative desulfurization performance of DBT (dibenzothiophene).
本文报道了一种一步合成小尺寸杯状中空ZSM-5单晶的方法。表征方法表明，产物具有典型的ZSM-5结构，大多数晶体是均匀的、单分散的晶体壳，具有明显的中空结构。单晶的平均尺寸约为350nm。每个杯状中空ZSM-5晶体在反应中都可作为微反应器，且基于ZSM-5的催化剂POM-MOF-ZSM-5（多金属氧酸盐（POM）、金属有机框架（MOF））对二苯并噻吩（DBT）表现出优异的氧化脱硫性能。
