Identification of Highly Active Co–O–Zn Sites in Silanol Nests for n -Butane Cascade Dehydrogenation to 1,3-Butadiene

-butane adsorption and activation of the C-H bond during both BDH and 1-butene dehydrogenation. Our work demonstrates a promising pathway for producing 1,3-BD via BDH using a catalyst that is free of expensive noble metals.
