Converting CO2 into high-value C2 chemicals such as acetate with high selectivity and efficiency is a critical issue in renewable energy storage. Herein, for the first time we present vibration-driven piezocatalysis tin(II) monosulfide (SnS) nanobelts conversion of to 100 % selectivity, highest production rate (2.21 mM h-1 ) compared reported catalysts. Mechanism analysis reveal that polarized charges triggered by periodic mechanical vibration promote adsorption activation . The electron transfer can be facilitated due built-in electric field, decreased band gap work function SnS under stress. Remarkably, reduced distance between active sites leads charge enrichment on Sn sites, promoting C-C coupling, reducing barriers determining step. It puts forward bran-new strategy converting products efficient, low-cost environment-friendly utilizing energy.

Abstract Heterojunctions are sustainable solutions for the photocatalytic CO 2 reduction reaction (CO RR) by regulating charge separation behavior at interface. However, their efficiency and product selectivity severely hindered inflexible weak built‐in electric field electronic structure of two phases. Herein, ferroelectric‐based heterojunctions between polarized bismuth ferrite (BFO(P)) CdS constructed to enhance interfacial interactions catalytic activity. The intrinsic polarization depending on ferroelectric state causes significant electrostatic potential difference energy‐band bending. This helps overcome unsatisfactory redox that differs from classical mechanism, synergy heterostructure facilitates effective transfer photogenerated charges with an extended lifetime (>20 ns) significantly enhanced photovoltage (1002 times BFO). optimized carrier dynamics allow heterojunction achieve a much higher yield compared state‐of‐the‐art photocatalysts, 85.46 23.47 than those pristine BFO, respectively. Moreover, it maintains impressive 100% together excellent repeatability cycling. work not only sheds light how strong inherent polarity promotes performance photocatalysts but also provides new insights designing efficient RR.
