Paper Title:
The Effect of Concentration of Phosphoric Acid on the Degree of Reduction of VPO Catalyst
  Abstract

Making VPO catalyst in the condition of different concentrations of Phosphoric acid and the temperatures,determine the average valence of vanadium. with the method of Potassium permanganate-Ferrous ammonium sulfate, to investigate the effect of different concentration of phosphoric acid on the average valence of catalyst, under the different temperatures. The structure, composition, crystal, and the Particle size has been characterized by XRD and SEM. The results confirmed that compare with higher concentration of phosphoric acid,the catalyst that were made with lower concentration phosphoric acid had the low average valence, greater specific surface area, better crystallinity, and more compact structure.
