Characterization, microbial and catalytic application of V2O5 nanoparticles prepared from Schiff base complexes as precursor

Vanadium pentoxide (V2O5) nanoparticles have gained much attention due to their simple synthesis, a wide range of chemical, industrial, biological, and medicinal applications including anti-inflammation, anti-oxidant, anti-microbial activities. Vanadium complexes of Schiff bases were used as a precursor to synthesis vanadium pentoxide (V2O5) nanoparticles. The precursor Schiff base complexes were obtained by mixing vanadyl acetylacetonate with the prepared Schiff base ligands maintaining a ratio 1:1. After that V(2)O(5)nanoparticles (denoted by C-1, C-2, C-3 and C-4) were synthesized by the direct calcination method based on thermal evaporation-condensation of vanadium complexes at 600 degrees C for 3 h. Finally, the analytical tools such as FTIR, XRD, EDS and SEM provided evidence in favor of the formation of V(2)O(5)nanoparticles. In addition, microbial study and photocatalytic activity were carried out using a spectrophotometer. An antimicrobial study showed that all the prepared V(2)O(5)nanoparticles have inhibition capacity against the growth of some selected human pathogenic bacteria and few of them against plant pathogenic fungi. Moreover, these V(2)O(5)nanoparticles have photocatalytic activity since these particles degrade organic dye, Eosin yellow. Graphic abstract
