      Vanadiumpentoxide (V2O5) nanoparticles have gainedmuch attention due to their simple synthesis, a wide range of chemical, industrial, biological, and medicinal applications including anti-inflammation, antioxidant, anti-microbial activities. Vanadium complexes of Schiff bases were used as a precursor to synthesis vanadiumpentoxide (V2O5) nanoparticles. The precursor Schiff base complexeswere obtained by mixing vanadyl acetylacetonate with the prepared Schiff base ligands maintaining a ratio 1:1. After that V2O5 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 °C for 3 h. Finally, the analytical tools such as FTIR, XRD,EDS and SEMprovided evidence in favor of the formation of V2O5 nanoparticles. In addition,microbial study and photocatalytic activity were carried out using a spectrophotometer. An antimicrobial study showed that all the prepared V2O5 nanoparticles have inhibition capacity against the growth of some selected human pathogenic bacteria and few of them against plant pathogenic fungi. Moreover, these V2O5 nanoparticles have photocatalytic activity since these particles degrade organic dye, Eosin yellow
