Interfacial Sites in Ag Supported Layered Double Oxide for Dehydrogenation Coupling of Ethanol to n‐Butanol

Abstract Upgrading of ethanol to n‐butanol through dehydrogenation coupling has received increasing attention due to the wide application of n‐butanol. But the enhancement of ethanol dehydrogenation and followed coupling to produce high selectivity to n‐butanol is still highly desired. Our previous...
