The Modification of VPO Catalyst Precursor and Characterization

Article Preview

Abstract:

Tween 60 and Tween 80 as dispersant had been adding in the preparation process to increase the surface area of VPO catalysts. XRD、 XPS and TEM characterization tests show that the crystalline phase and the catalyst surface area of adding surfactant Tween 60 and Tween 80 are different from that did not. Although the two types of crystalline phase are to (VO)2P2O7 but their microscopic structures are different and found that the surface area of the former is 35-40m2 / g, while the surface area without adding surfactants is only 19m2 / g.
