Synergistic effect of Zn–N coordination inducing enhanced hydrophobicity and dipole activation for efficient photocatalytic ROS evolution

Abstract

The formation of Zn–N bonds and the deposition of ZnO synergistically enhanced both hydrophobicity and the molecular dipole, promoting efficient oxygen enrichment and electron utilization, which significantly improved ROS generation. This enabled H₂O₂ production and effective mineralization of sulfamethoxazole, highlighting the crucial role of microenvironment engineering in solar-driven water purification.
