Abstract

The development of highly efficient and stable photocatalysts for solar-driven hydrogen peroxide (H₂O₂) production represents a pivotal direction in green chemistry research. Herein, we report the successful synthesis of a novel silver-based metal-organic framework (MOF) photocatalyst, Ag-TEPT (where TEPT=2,4,6-tris(4-ethynylphenyl)- 1,3,5-triazine), which was constructed via a metal-carbon (M—C) bond coordination strategy to bridge Ag(I) clusters with triazine-based linkers. Under simulated sunlight irradiation, Ag-TEPT exhibited an outstanding H₂O₂ production rate of 2880 μmol•g⁻¹•h⁻¹ in a pure water-oxygen system without any sacrificial agents, a performance that significantly surpasses most reported photocatalysts. Impressively, it maintained a high production rate of 2024 μmol•g⁻¹•h⁻¹ even in ambient air. Furthermore, Ag-TEPT demonstrated remarkable photocatalytic stability with negligible activity loss over three consecutive reaction cycles. Post-catalytic characterization confirmed its unvaried crystal structure, morphology, and surface chemical states, attesting to its potential as a high-performance and durable photocatalyst. Mechanistic studies revealed a dual-pathway reaction mechanism, wherein H₂O₂ generation proceeds via simultaneous 2e⁻ oxygen reduction reaction (ORR) and 4e⁻ water oxidation reaction (WOR) processes. Notably, the O₂ produced from the 4e⁻ WOR serves as an internal feedstock for the 2e⁻ ORR, mitigating the dependency on exogenous O₂ and thereby enhancing the overall catalytic efficiency. In addition, the band structure of AgC-MOF, constructed from Tauc plot fitting and Mott-Schottky measurements, provided thermodynamic validation that Ag-TEPT is suitable for the photocatalytic reduction of O₂ to H₂O₂ and the oxidation of H₂O to O₂, but not for the direct oxidation of H₂O to H₂O₂. Photoluminescence spectroscopy and photoelectrochemical measurements confirmed the exceptional photogenerated charge separation efficiency of AgC-MOF, a benefit derived from the superior electron transport capability of the Ag-alkynyl bonds, which led to markedly improved photocatalytic reaction kinetics. In particular, Ag-TEPT showed a substantially higher photocurrent density, attributable to the excellent photosensitivity of the triazine units within the TEPT linker.
