Synthesis, characterization of Co1-xNixAl2O4 Spinel system and catalytic role in the synthesis of dihydropyrimidinone

Abstract

In the present investigation, Spinel systems with chemical composition Co1 − xNixAl2O4 (x = 0.0, 0.25, 0.5, and 0.75) have been successfully synthesized by the co-precipitation citrate precursor technique. The phase formation, crystal structure, and impurity check were confirmed by X-ray powdered diffraction (XRD) and Fourier transforms infrared (FTIR) spectroscopy technique. The particle size estimation was done using a transmission electron microscope (TEM). Investigation of magnetic behavior and parameters such as saturation magnetization (MS), coercivity (HR), and retentivity (MR) was done using a vibrating sample magnetometer (VSM). The catalytic activity of prepared spinel systems was explored for the one-pot synthesis of dihydropyrimidinone derivatives. The catalytic product was identified by comparison of melting point and the spectral data (FTIR).

“…Within the series of LaMO 3 oxides (M, first-row transition metal), LaCoO 3 has the greatest catalytic activity for oxidation of CO, propene, and isobutene . PrCoO 3 , with its lower oxygen binding energy, should exhibit more catalytic activity than LaCoO 3 …”
