Project Description: With the recent boom in the shale gas production, we have an abundant source of light alkanes. The successful dehydrogenation of alkanes to alkenes is currently being catalyzed by Pt bimetallic compounds like Pt-Sn. Recently, Pd, a transition metal which is closer to Pt in the reactivity towards catalytic reforming has been reported to perform well for light alkane dehydrogenation. As with Pt, Pd has also been seen to perform poorly without the addition of promoters like Zn, In. To make it a ubiquitous catalyst, the reactivity of different Pd intermetallic compounds relative to each other is to be estimated. The aim of the study undertaken is to establish the reactivity and the selectivity of different Pd bimetallic compounds like PdIn, PdSn, and PdZn with respect to Pd towards the dehydrogenation of different lighter alkanes and how they change the selectivity of the Pd metal surface towards C-H and C-C bond activation.
