A Rigaku Benchtop Miniflex X-ray diffraction (XRD) diffractometer (Tokyo, Japan) with Cu Kα radiation at room temperature (RT) over the 2θ range from 20° to 70° was used for the structural analysis. Scanning electron microscopy (SEM, FEI Titan ST, Hillsboro, OR, USA) along with energy dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM; FEI, Morgagni 268, Prague, Czech Republic) were used for the morphological and composition analyses. Spectral analysis of all products was performed via Fourier transform infrared (FT-IR) spectroscopy (Bruker, Berlin, Germany). Ultraviolet-visible (UV-vis) diffuse reflectance (DR%, Shimadzu, Tokyo, Japan) spectra were recorded in the 200 to 800 nm wavelength range using a DR spectrophotometer. The magnetic properties of the products were measured using a Quantum Design SQUID-PPMS vibrating sample magnetometer (PPMS DynaCool, Quantum Design, San Diego, CA, USA).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
