Butane Dry Reforming Catalyzed by Cobalt Oxide Supported on Ti₂ AlC MAX Phase.

ABSTRACT: MAX (M_n+1 AX_n ) phases are layered carbides or nitrides with a high thermal and mechanical bulk stability. Recently, it was shown that their surface structure can be modified to form a thin non-stoichiometric oxide layer, which can catalyze the oxidative dehydrogenation of butane. Here, the use of a Ti₂ AlC MAX phase as a support for cobalt oxide was explored for the dry reforming of butane with CO₂ , comparing this new catalyst to more traditional materials. The catalyst was active and selective to synthesis gas. Although the surface structure changed during the reaction, the activity remained stable. Under the same conditions, a titania-supported cobalt oxide catalyst gave low activity and stability due to the agglomeration of cobalt oxide part
