Data for: Controllable synthesis of 3D spicate Fe36Co64 alloy microstructures as superior cyclicity and magnetically recyclable catalyst for p-nitrophenol reduction

The structure information of the samples was characterized by X-ray diffraction (XRD, Shimadzu XRD-6000, Cu–Kα radiation, λ = 1.5406 A˚ with 2θ values from 20° to 90°. The operation voltage and current were kept at 40 kV and 30 mA), the morphology and composition were collected by scanning electron microscopy (SEM, Hitachi S-4800) and energy dispersive X-ray spectroscopy (EDS, INCAx-Sight OXFORD) attached to SEM. Transmission electron microscopy (TEM) and high resolution TEM (HRTEM) were measured using JEM JEOL-2010 at 200 kV. The magnetic information was analyzed by superconducting quantum interference device (SQUID, MPMS-XL-7) with a maximum magnetic field of 20 kOe. UV-vis spectra were monitored by a Hitachi U-4100 spectrometer.
