N2 - This contribution reports on the biosynthesis of the n-type Bismuth vanadate (BiVO4) nanorods prepared via the use of aqueous extracts of Callistemon viminalis as an effective chelating agent. To ascertain the formation of crystalline and pure BiVO4nanorods, various surface & interface characterization were performed on annealed BiVO4powders. X-Ray Diffraction analysis showed that the BiVO4nanorods obtained after annealing at 500°C, were of high purity and polycrystalline in nature. The morphological analysis revealed that the basal & longitudinal dimensions of the obtained BiVO4nanorods ranged from 350 to 450nm and 1.2-2µm, respectively. The effect of the annealed BiVO4nanorods on the photocatalytic degradation of methylene blue (MB), a model pollutant, was evaluated with obtained results suggesting that the degradation of Methylene Blue in the presence of BiVO4nanorods occurs at an efficiency of 82% under Solar Visible after 5h, at room temperature. These results show that bio-synthesized BiVO4prepared using plant extracts of Callistemon viminalis could be a promising method for the synthesis of functional nanomaterials that find use as photocatalysts.
