Abstract

Synthesis of V2O5 nanoparticles (NPs) using Calophyllum inophyllum leaf extract (CILE) as an eco-friendly material has been investigated. V2O5 NPs were prepared using NH4VO3 as precursor. The typical absorption peak of V2O5 NPs has been characterized using UV-Vis spectrophotometer at 204 nm. V2O5 NPs have the band gap value of 2.42 eV confirmed by UV-Visible Diffuse Reflectance Spectroscopy (UV-vis DRS). X-ray diffraction (XRD) analysis shows that an average crystal size of V2O5 NPs was 68 nm. Identification of functional groups was characterized by Fourier-Transform Infrared (FTIR) spectroscopy. The absorption band at 1023 cm-1 shows the V=O bond and the V-O-V bond at 849 and 578 cm-1, respectively. Size distribution of V2O5 NPs was characterized by particle size analyzer (PSA). Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) Spectroscopy analysis was used to determine the morphological and the element composition of V2O5NPs. The degradation percentage of methylene blue (MB) using V2O5 NPs was 74.83 % under visible light irradiation for 120 min.
