Abstract

Abstract: The selective bio‐ethanol cascade transformation to hydrocarbons over multifunctional catalysts is a highly promising sustainable pathway to high‐value chemicals and fuels. However, principles to control the selectivity of the bio‐ethanol transformation using the effects of the size of nanoparticle catalysts have remainedlargely unexplored. Here, using bio‐ethanol transformation reactions catalyzed by Au/ZnZr10 Ox as examples, we demonstrate that changing the fashion of gold loading enables control over product distribution. Our results reveal that larger gold particles tendto show much higher selectivity for 1, 3‐butadiene, whereas smaller gold nanoparticles favor the formation of acetaldehyde.This study uncovers general principles for tailoring the selectivity of bio‐ethanol transformation by carefully engineering the size of gold. It opens a new avenue for the rational design of multifunctional catalysts to enhance the production of desired reaction products in complex cascade reaction sequences. Abstract : Gold goes bio : The selective bio‐ethanol cascade transformation to hydrocarbons over multifunctional catalysts is a highly promising sustainable pathway to high‐value chemicals and fuels. Bio‐ethanol can be transformed efficiently into either acetaldehyde by initial ethanol dehydrogenation or 1, 3‐BD, depending on the fashion of gold loading on a ZnZr10 Ox support. Larger gold particles tend to show much higher selectivity for 1, 3‐butadiene, whereas smaller gold nanoparticles favor the formation of acetaldehyde.
