摘要

在H-Y分子筛上首次观察到乙烯吸附的关键中间体，即表面乙氧基。通过结合选择性13c标记协议和多技术方法，我们证实了表面乙氧基物种的关键作用，即在第一步与乙烯平衡，并进一步烷基化形成C-C键。

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 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.
