| چکیده | ||
| Synthesis of Cu2V2O7 nanoparticles was performed successfully using Cu(NO3)2 and V2O5 raw compounds in one step solid state method. Cu2V2O7 nano powders were used as photocatalysts to remove pollutant dye under visible light irradiation. X-ray diffraction (XRD) technique was applied to characterize the crystal phase type of the as-prepared sample. The XRD results showed that the patterns had a main Cu2V2O7 structure with a space group of C2/c. Field emission scanning electron microscopy (FESEM) images showed that the synthesized Cu2V2O7 particles had mono-shaped sphere morphologies. The as-prepared Cu2V2O7 nanomaterial exhibited high catalytic activity in multi-component reaction for the one-pot synthesis of heterocyclic compound 3,4-dihydropyrimidin-2(1H)-ones (DHPMs). Additionally, the nanocatalyst can be reused for several times without apparent loss of its catalytic activity, confirming it is a highly stable and reusable material for this reaction. It is found that the optimum values for catalyst amount, reaction time and temperature are 50 mg, 50 min and 90 ºC, respectively. | ||
