New Spectroscopy Findings from University of Putra Malaysia Described (Influence of Zn/Fe Molar Ratio on Optical and Magnetic Properties of ZnO and ZnFe2O4 Nanocrystal as Calcined Products of Layered Double Hydroxides)

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Spectroscopy. According to news reporting originating from Selangor, Malaysia, by NewsRx correspondents, research stated, "The coprecipitation method has been used to synthesize layered double hydroxide (Zn-Fe-LDH) nanostructure at different Zn2+/Fe3+ molar ratios. The structural properties of samples were studied using powder X-ray diffraction (PXRD)."

Our news editors obtained a quote from the research from the University of Putra Malaysia, "LDH samples were calcined at 600 degrees Cto produce mixed oxides (ZnOand ZnFe2O 4). The crystallite size of mixed oxide was found in the nanometer scale (18.1 nm for ZnFe2O4 and 43.3 nm for ZnO). The photocatalytic activity of the calcination products was investigated using ultraviolet-visible-near infrared (UV-VIS-NIR) diffuse reflectance spectroscopy. The magnetic properties of calcined LDHs were investigated using a vibrating sample magnetometer (VSM). The calcined samples showed a paramagnetic behavior for all Zn2+/Fe3+ molar ratios."

According to the news editors, the research concluded: "The effect of molar ratio on magnetic susceptibility of the calcined samples was also studied."
