Direct and Oriented Conversion of CO2 into Value‐Added Aromatics

Abstract The oriented conversion of CO 2 into target high‐value chemicals is an effective way to reduce carbon emissions, but still presents a challenge. In this communication, we report the oriented conversion of CO 2 into value‐added aromatics, especially para ‐xylene, in a single pass by combining core–shell structured Zn‐doped H‐ZSM‐5 (Zn‐ZSM‐5@SiO 2 ) and a Cr 2 O 3 component. Through precise regulation of the acidity of Zn‐ZSM‐5@SiO 2 , high para ‐xylene selectivity (38.7 % in the total products) at a CO 2 conversion of 22.1 % was achieved. Furthermore, a CO 2 ‐assisted effect in the synthesis of aromatics during the tandem process has been clarified through a control experiment. The CO 2 reactant can act as a hydrogen acceptor to accelerate the dehydrogenation of alkenes, intermediates in the synthesis of aromatics, thereby increasing the driving force towards aromatics in the tandem reaction process.
