文摘

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 Fe₃O₄ 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鈥? 渭m), ultrafine uniform Fe₃O₄ NPs (10 nm), good structural stability, high surface area (340 m²/g), and large magnetization (8.6 emu/g) and exhibit a potential application in Fischer鈥揟ropsch synthesis.
