📄 Abstract（原文）
Hydrogen peroxide (H2O2) is a critical industrial chemical traditionally produced via the energy‐intensive anthraquinone process. Here, we report a low‐cost (<$0.6/g), hydroxyl‐functionalized metal‐organic polymer (MIL‐2OH‐W) featuring abundant undercoordinated [WO6]6− centers for solar‐driven H2O2 production. MIL‐2OH‐W achieves a record production rate of 11.25 mmol·g−1·h−1 in the first 10 min and becomes saturated to 3 mmol·g−1·h−1 in 1 h, reaching a concentration of 1.02 g·L−1 (30 mmol·L−1) with a 2.74% solar‐to‐chemical efficiency under mild conditions (40°C). Mechanistic studies from in‐situ transient absorption, in‐situ infrared, in‐situ electron paramagnetic resonance and density functional theory reveal a synergistic photothermal pathway, where aromatic hydroxyl linkers mimic anthraquinone‐like redox cycling, stabilize radical intermediates, and accelerate oxygen reduction. The catalyst exhibits exceptional stability (>40 days) and scalability, aligning with the United Nations decarbonization goals. This work provides a blueprint for sustainable H2O2 synthesis by integrating photothermal catalysis with waste‐heat utilization.
