摘要：

Chain-like ZSM-5 zeolite with long b-axis length and mesoporosity has been synthesized rapidly and efficiently in supercritical CO2. X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM) images demonstrate that chain-like ZSM-5 zeolite has good crystallinity and chain-like morphology. N2 sorption isotherm indicates that chain-like ZSM-5 has mesopores. The formation of p-xylene from m-xylene isomerization has been tested in catalytic paltform, showing that chain-like ZSM-5 has higher conversion of m-xylene and selectivity of p-xylene, due to the combination of the long b-axis length and the mesoporosity in the chain-like ZSM-5 sample, compared with conventional ZSM-5 zeolite.
