[Display omitted] Confronting the challenge of climate change necessitates innovative approaches for the reduction of CO 2 emissions. Metal-support interaction has been widely demonstrated to enable greatly improved performances in thermal-catalytic, photocatalytic and electrocatalytic CO 2 reduction. However, its applicability and specifically its role in the emerging piezo-electrocatalytic CO 2 reduction are unknown, severely hampering the utilizations of piezo-electrocatalysis in CO 2 conversion. Herein, by adopting Au particles supported on ZnO (Au/ZnO) as a paradigm, it is found that the metal-support interaction can remarkably improve the separation and transfer of piezo-carriers and enhance CO 2 adsorption. As a result, Au/ZnO demonstrates a substantially boosted activity for piezo-electrocatalytic CO 2 reduction and the optimal sample exhibits a 37.3% increase in CO yield compared to the pristine ZnO. The integration of metal-support interactions opens a new avenue to the design of advanced piezo-electrocatalysts for CO 2 reduction. [ABSTRACT FROM AUTHOR]
