Abstract

Fe3O4/ZIF-8 composites were synthesized to examine how magnetic core loading affects crystallization, lattice strain, and structure. XRD shows a shift in the ZIF-8 (011) peak from compressive to tensile strain with increasing Fe3O4, indicating interfacial coordination with Zn2+. Crystallite size reduction confirms heterogeneous nucleation, with an anomaly at intermediate loading due to agglomeration. Raman spectra exhibit redshifts, strongest (~6 cm−1) in the imidazole mode, with peak overlap from Fe3O4 confirming linker-level interaction. The Zn−N framework remains intact, and magnetic responsiveness is preserved.
