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.

Converting carbon dioxide into fuel and chemicals by utilizing solar energy represents a cutting-edge approach to recovery renewal. The transfer behavior of photogenerated electrons built-in electric field photocatalysts greatly affect the efficiency photoreduction reaction. Herein, heterostructures composed bismuth sodium titanate (BNT) ferroelectrics silver nanoparticles (Ag NPs) are constructed promote photocatalytic CO2 performance. large spontaneous polarization BNT optimizes dynamics photoinduced holes causes band bending with strong intrinsic field. With aid Ag NPs, BNT@xAg heterojunctions exhibit intensified light absorption due phenomenon localized surface plasmon resonance (LSPR), which extends visible spectrum strengthens charge transfer. modified catalysts demonstrate improved separation capacity notably prolonged electron lifetime up 40.95 ns. synergistic effect LSPR significantly boosts together ultrahigh CO product selectivity, is outstanding among ferroelectric other representative photocatalysts. This study elucidates enhancement mechanism plasmonic decorated offers an alternative route for design efficient catalysts.
