Abstract: Water cont ami nationby persist^t organic pollutants poses a sWous~tKreat"fo environmental sustainability and public health, necessitating the development of efficient remediation technologies. Among these pollutants, 2,4-dichlorophenoxyacetic acid (2,4-D), a widely used herbicide, is of particular concern due to its environmental persistence, potential toxicity, and adverse effects on aquatic ecosystems and biodiversity. In this study, a novel Zn-BTC metalorganic framework/graphitic carbon nitride (Zn-BTC MOF/g-C3N4) hybrid photocatalyst was successfully synthesized by integrating Zn-BTC MOF with g-C3N4 nanosheets to enhance visible-light- driven photocatalytic performance. Comprehensive characterization using UV-Vis spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy confirmed the successful formation of the heterostructured composite, accompanied by improved light absorption, reduced band-gap energy, and increased surface-active sites. The Zn-BTC MOF/g-C3N4 composite exhibited remarkable photocatalytic activity, achieving approximately 98% degradation of 2,4-D within 120 min under visible-light irradiation, significantly outperforming the individual components. The enhanced performance is attributed to the formation of an efficient Z-scheme heterojunction, which promotes rapid charge separation, facilitates directional electron transfer, and suppresses electron-hole recombination while preserving strong redox capability. Kinetic studies revealed pseudo-first-order degradation behavior, whereas radical trapping experiments identified photogenerated holes (h^) and superoxide radicals ( 02") as the dominant reactive species. Furthermore, the composite demonstrated excellent stability and reusability over multiple cycles. These findings highlight the potential of Zn-BTC MOF/g-C3N4 as a robust and sustainable photocatalyst for pesticidecontaminated wastewater treatment.
