Abstract
A new family of nitrided phosphates, the oxynitrides (Ga,Al)PON, have been prepared by nitridation under ammonia flow in the 500-1000 degrees C temperature range of galloaluminophosphates obtained by sol-gel route. These (Ga,Al)PON oxynitrides, in which the P/(Ga + Al) atomic ratio and the nitrogen content can vary both, are amorphous powders characterized by high specific surface areas up to 300 m(2) g(-1). These new materials have been tested as supported platinum catalysts in the isobutane dehydrogenation and compared to other catalysts: The Pt/(Ga,Al)PON catalysts present the highest conversion and selectivity rates in isobutene.
