Abstract
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 13C-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.
