摘要：Chlorophenols are typical refractory organic pollutants that are hard to remove by conventional photocatalysis due to rapid charge recombination and insufficient reactive oxygen species (ROS) generation. Piezo-photocatalysis is promising but limited by lack of understanding regarding interfacial chemical bonding and atomic orbital interactions in dual-piezoelectric heterojunctions. Here, an interfacially coupled BiFeO3/ZnIn2S4 dual-piezoelectric heterojunction catalyst was fabricated. Bi–S p–p orbital hybridization forms a stable interfacial electronic bridge that enhances the stability of the catalyst. Strain-induced polarization enhances the dipole moment, promoting the adsorption and activation of H2O and O2. This system drives the degradation of 2,4-dichlorophenol (2,4-DCP) through synergistic reactions. This work not only resolves the shortcoming of poor interface stability in traditional piezo-photocatalysts but also enhances the understanding of the mechanistic relationship between orbital hybridization and piezo-photocatalytic activity. It provides a design strategy for orbital hybridization between interfacial atoms for unique dual-piezoelectric heterojunction catalysts aimed at sustainable water decontamination.
