Abstract The recent shale gas boom combined with the requirement to reduce atmospheric CO 2 have created an opportunity for using both raw materials (shale gas and CO 2 ) in a single process. Shale gas is primarily made up of methane, but ethane comprises about 10 % and reserves are underutilized. Two routes have been investigated by combining ethane decomposition with CO 2 reduction to produce products of higher value. The first reaction is ethane dry reforming which produces synthesis gas (CO+H 2 ). The second route is oxidative dehydrogenation which produces ethylene using CO 2 as a soft oxidant. The results of this study indicate that the Pt/CeO 2 catalyst shows promise for the production of synthesis gas, while Mo 2 C‐based materials preserve the CC bond of ethane to produce ethylene. These findings are supported by density functional theory (DFT) calculations and X‐ray absorption near‐edge spectroscopy (XANES) characterization of the catalysts under in situ reaction conditions.
