Propane dehydrogenation over Pt–Cu bimetallic catalysts: the nature of coke deposition and the role of copper

This paper describes a promotional effect of Cu on the catalytic performance of Pt/Al 2 O 3 catalysts for propane dehydrogenation. The Pt–Cu interaction inhibits propylene adsorption and suppresses C–C bond rupture, leading to the enhanced catalytic performance of the Pt–Cu/Al 2 O 3 catalyst.
