<p>The catalytic properties of reduced graphene oxide (rGO) deposited on aluminium oxide in the ethane dehydrogenation reaction have been studied. It is shown that the deposition of 1wt.% of rGO on aluminium oxide increases the ethane conversion when compared to a pure support. The rGO/Al₂O₃ catalyst exhibits 100% selectivity for ethylene at temperatures below 650°C. Based on the use of Raman and infrared spectroscopy, as well as nitrogen adsorption and desorption isotherms, the structural characteristics before and after the dehydrogenation process have been determined, and the carbonization of rGO/Al₂O₃ and the initial Al₂O₃ during ethane dehydrogenation has been confirmed. Carbonization of the catalyst does not lead to a complete loss of its activity, which may be associated with the formation of graphene-like nanostructures, which also reveal catalytic activity.</p>
