摘要：Developing highly efficient and robust photocatalysts for concurrent solar energy conversion and complex wastewater remediation remains a formidable challenge. Herein, a rationally designed carbon-bridged ternary Sscheme heterojunction (In2O3/C/ZnIn2S4) was successfully constructed. This was achieved via the in-situ hydrothermal growth of ZnIn2S4 nanosheets onto MOF-derived (MIL-68(In)) In2O3/C nanorods. The inserted carbon layer acts as an efficient interfacial charge-transfer bridge, significantly enhancing the separation and migration of photogenerated carriers. The optimal composite (IO/C/ZIS-15) demonstrated exceptional visible-light-driven photocatalytic hydrogen evolution activity (9.03 mmol g-1 h-1), which markedly outperformed its individual components. Furthermore, the catalyst exhibited robust and versatile degradation capabilities for mixed pollutants, including tetracycline hydrochloride (TC), nitrofurantoin (NFT), and Cr(VI), under various challenging conditions such as high pollutant concentrations, diverse ionic interferences, a broad pH range, and simulated real wastewater matrices. Mechanistic investigations, including photoelectrochemical measurements, active species trapping, ESR, and in-situ XPS analysis, revealed an S-scheme charge transfer pathway mediated by the carbon bridge. This pathway not only improves carrier separation but also preserves strong redox potentials, facilitating the generation of critical reactive species (center dot O2-and center dot OH) for efficient redox reactions. This work provides a strategic design for high-performance ternary photocatalysts with integrated carbon mediators, offering promising potential for addressing concurrent energy and environmental remediation needs.
