(VO)2P2O7 (VPO) is known to act as a heterogeneous catalyst in the oxidation of n-butane to maleic anhydride. DuPont has developed a new circulating fluid bed process for this reaction, and first commercial plant using this technology is scheduled to start up in early 1996. VPO catalyst is typically formed by transforming the vanadyl hydrogen phosphate precursor (VOHPO4. 1/2H2O) to the vanadyl pyrophosphate active phase. It was the object of the current study to develop a more fundamental understanding of this phase transformation.Transformation conditions were 500° - 700° C in nitrogen. The hydrated precursors used in this study were in the form of plate-shaped single crystals. The crystallographic convention is given in Table 1. Microstructural and morphological changes associated with the phase transformation were studied at scales ranging from the mm to the nm range using scanning electron microscopy (Hitachi S-4000) and transmission electron microscopy (JEM 2000FX). Figure la is an SEM showing the corner of a precursor crystal plate with the c axis indicated.
