چکیده | ||
Nanostructured Mn2Sb2O7 powders were synthesized via stoichiometric1:1 Mn:Sb molar ratio solid state reaction at different reactions temperatures for 8 h using MnSO4.H2O and Sb2O3 as raw materials. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique. Structural analyses were performed by the FullProf program employing profile matching with constant scale factors. The results showed that the patterns had a main monoclinic Mn2Sb2O7 crystal structure with space group P21. The morphologies of the synthesized materials were studied by field emission scanning electron microscopy (FESEM) and Transmission electron microscopy (TEM) which showed that the Mn2Sb2O7 samples had flower like and spherical particles morphologies. Ultraviolet – Visible spectroscopy (UV-Vis) showed that the band gap was about 2.85 eV. The most pure sample (S6) was used as catalyst in the one-pot synthesis of the heterocyclic compounds 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) in Biginelli reactions. Experimental design was used to find the optimized reaction conditions. | ||
