- Abstract
Abstract: Silicalite-1 supported CrO<italic>x</italic> is highly active and stable for the ethane dehydrogenation with CO2, whose ethylene yield reached 37.8%, and only 9.5% of its initial activity was lost after 6 h, which can be attributed to the formation of single-site CrO<italic>x</italic> moieties embedded in the framework vacancy defects of zeolite. The strong interaction with silicalite-1 surface as well as the geometry isolation effect may account for the excellent activity and stability of single-site CrO<italic>x</italic> moieties.Graphical Abstract: <graphic></graphic>
