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.
在此，我们开发了一种可重复的原位结晶路线，用于合成由聚集的 ZSM-5 纳米棒和均匀分散的 Fe(3)O(4)纳米颗粒（NPs）组成的均匀功能 ZSM-5 微球。这种独特微球的生长经历了从表面到核心的 NP 辅助再结晶过程。所得到的磁性 ZSM-5 微球具有均匀的尺寸（6-9 μm）、超细微均匀的 Fe(3)O(4) NPs（10nm）、良好的结构稳定性、高表面积（340m(2)/g）和大磁化强度（8.6 emu/g），并在费托合成中表现出潜在的应用。
