在此，我们开发了一种可重复的原位结晶路线来合成均匀功能的ZSM-5微球，该微球由聚集的ZSM-5纳米棒和分散均匀的Fe(3)O(4)纳米颗粒（NPs）组成。这种独特的微球的生长经历了从表面到核心的np辅助再结晶过程。所制得的ZSM-5磁性微球具有粒径均匀（6-9 μm）、超细均匀的Fe(3)O(4) NPs （~10 nm）、结构稳定性好、比表面积高（340 m(2)/g）、磁化强度大（~8.6 emu/g）等特点，在费托合成中具有潜在的应用前景。
Herein, we develop a reproducible in situ crystallization route to synthesize uniform functional ZSM-5 microspheres composed of aggregated ZSM-5 nanorods and well-dispersed uniform Fe(3)O(4) nanoparticles (NPs). The growth of such unique microspheres undergoes a NP-assisted recrystallization process from surface to core. The obtained magnetic ZSM-5 microspheres possess a uniform size (6-9 μm), ultrafine uniform Fe(3)O(4) NPs (~10 nm), good structural stability, high surface area (340 m(2)/g), and large magnetization (~8.6 emu/g) and exhibit a potential application in Fischer-Tropsch synthesis.
