SYNTHESIS, CHARACTERIZATION AND m-XYLENE DECOMPOSITION CATALYST OF NdVO4 AND NdVO4:A3+ (A = Gd, Bi)

Abstract

      NdVO4 and NdVO4:A3+ (A = Gd, Bi) was synthesized by the combustion technique and characterized by X-ray diffraction, UV-vis spectroscopy, energy dispersion by X-rays, scanning electron microscopy and BET surface area analyzer. The degradation of m-xylene was studied over NdVO4 and NdVO4:A3+ compounds. The amount of A substituted was studied at 5%. All the compounds showed high oxidative activity towards m-xylene degradation, especially NdVO4.

Keywords: Neodymium vanadate, m-xylene, combustion technique.
