Vanadium oxide nanomaterials: catalyst for the decomposition of hazardous dye

Abstract

A new series of vanadium oxide nanomaterials were synthesized from vanadium metal complexes with different hydrazone derivatives obtain by condensation of 2-Hydroxy Benzoyl Hydrazide with substituted aromatic aldehydes viz. Salicylaldehyde, 5-Bromo Salicylaldehyde, 5-Chloro Salicylaldehyde, 5-Methoxy Salicylaldehyde and 5-Hydroxy Salicylaldehyde8. Vanadium metal complexes were heated at 700°C for three hours to obtain vanadium oxide nanoparticles by thermal decomposition. The properties such as size, morphology and crystallinity of as-synthesized nanoparticles were studied by powder XRD, FTIR and SEM images. The XRD patterns confirm the formation of vanadium oxide nanoparticles. The SEM images supports nanostructures and FTIR peaks indicated V-O bonding in the present vanadium oxides nano-materials.
