Paper Abstract

Heteropolyacids (HPAs) are compounds widely applied in different catalytic processes. They have been used as acid catalysts and also as oxidation catalysts at elevated temperatures. Therefore, from the catalytic point of view it is important to know the thermal behavior of these compounds under reduction and oxidation conditions as well. Although several studies on the thermal properties have been reported, also by means of in situ IR spectroscopy, little is known about decomposition of HPAs, in controlled atmosphere. In this study we examined in situ by DRIFT spectroscopy the solid state heteropolyacids at temperature range 295 K - 723 K in both dry nitrogen and oxygen atmospheres.
