Abstract

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 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 SEM provided 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.

以席夫碱配合物为前驱体制备的V 2 O 5纳米颗粒的表征,微生物和催化应用

摘要

五氧化二钒(V 2 O 5)纳米颗粒由于其简单的合成,广泛的化学,工业,生物和医学应用(包括抗炎,抗氧化,抗微生物活性)而备受关注。Schiff碱的钒配合物用作合成五氧化二钒(V 2 O 5)纳米粒子的前体。前驱体席夫碱配合物是通过将乙酰丙酮氧钒与保持比例为1:1的席夫碱配体混合而获得的。之后,V 2 O 5以钒配合物在600°C下热蒸发-冷凝3 h为基础,通过直接煅烧法合成了纳米颗粒(以C-1,C-2,C-3和C-4表示)。最后,诸如FTIR,XRD,EDS和SEM之类的分析工具为形成V 2 O 5纳米粒子提供了证据。另外,使用分光光度计进行了微生物研究和光催化活性。一项抗菌研究表明,所有制备的V 2 O 5纳米颗粒均具有抑制某些选定的人类致病细菌生长的能力,而几乎没有针对植物致病真菌的生长能力。此外,这些V 2 O 5 纳米颗粒具有光催化活性,因为这些颗粒会降解有机染料曙红黄。
