2026-06-08 The Synthesis of ZSM-5 Nanosheets and Its Catalytic Performance for n-Hexane Cracking doi:10.57760/sciencedb.39359 en ZSM-5 nanosheets with high crystallinity were successfully synthesized at low-cost using the diquaternary ammonium surfactant (C18-6-3) extracted from as-synthesized ZSM-5 nanosheets as structure-directing agent (SDA). The physicochemical properties of the zeolite nanosheets, including morphology, pore architecture, and acidity, were systematically characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning/transmission electron microscopy (SEM/TEM), NH3 temperature-programmed desorption (NH3-TPD), and low-temperature N2 physisorption. Their catalytic performance was evaluated in the n-hexane cracking reaction. The results demonstrated that the extraction of C18-6-3 did not influence the textural properties of the parent ZSM-5 nanosheets. By using the extracted C18-6-3 as SDA, the synthesized ZSM-5 nanosheets exhibit not only high crystallinity and high mesopore volume, but also excellent performance in the catalytic conversion of n-hexane. This strategy substantially reduced the consumption of the expensive C18-6-3 surfactant and lowered the cost of synthesizing ZSM-5 nanosheets. zeolite; nanosheet; extraction; low-cost; catalytic cracking Zhu Xiaochun Mei Boxiang Zhang Tengyue Wang Jiujiang Zhao Hongjuan Zhang Lei Liu Honghai Shen Baojian PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/10.16084/j.issn1001-3555.2026.01.003 Science Data Bank
