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.
