An efficient robust fluorite CeZrO_4−δ oxide catalyst for the eco-benign synthesis of styrene

Abstract

The catalytic activities of CeO₂, ZrO₂, (PH)-CeO₂/ZrO₂ and fluorite CeZrO_4−δ oxides were reported for the oxidative dehydrogenation of ethyl benzene to styrene using O₂, air and CO₂ as oxidants. CeZrO_4−δ accounted for a 47% styrene yield under optimized reaction conditions.
