Propene and diisopropyl ether resulted the main reaction products. The (photo)catalysts were bare and supported Keggin H3PW12O40 and Wells-Dawson H6P2W18O60 heteropolyacids (HPAs). Boron nitride (BN) and carbon nitride (C3N4) were used as supports. The HPA species played the key role both in the catalytic and photocatalytic reactions. The acidity of the cluster accounts for the catalytic role, whereas both the acidity and the redox properties of the HPA species were responsible for the increase of the reaction rate in the photo-assisted catalytic reaction. The supported HPAs resulted more active than pristine heteropolyacids. The propene reaction rate increased by irradiating the catalytic system. The Wells-Dawson HPA was more active than the Keggin one both as catalyst and as photocatalyst, as previously observed [1]. The BN support resulted beneficial in comparison to C3N4. The apparent activation energy for the catalytic and photocatalytic dehydration has been determined resulting always lower for the photocatalytic process than for the catalytic one. [1] E. I.
