Observation of reactive intermediates in the initial stage during ethene conversion over acidic zeolites

The key intermediates, i.e. , surface ethoxy species, were observed upon the adsorption of ethene on zeolite H-Y for the first time. By combining a selective 13 C-labeling protocol with a multitechnique approach, we confirmed the critical role of surface ethoxy species, that is, equilibrium with eth...

Description
Summary:The key intermediates, i.e. , surface ethoxy species, were observed upon the adsorption of ethene on zeolite H-Y for the first time. By combining a selective 13 C-labeling protocol with a multitechnique approach, we confirmed the critical role of surface ethoxy species, that is, equilibrium with ethene in the primary step and further alkylation to form the C-C bond. The surface ethoxy species were identified as key intermediates to equilibrate with ethene and contribute to the formation of the initial C-C bond during the ethene conversion on acidic zeolites.
