| 其它 | Abstract：Solar-driven synthesis of hydrogen peroxide (H2O2) from water and O2 represents a sustainable and cost-effective alternative to conventional processes. However, the weak redox capacity and rapid carrier recombination in single-component photocatalysts remain significant bottlenecks. Here, rational strain engineering coupled with internal electric field intensification strategy to enhance photocatalytic H2O2 generation by constructing an S-scheme heterojunction is reported. This is achieved via the in situ growth of CdSe nanowires, modulated by diethylenetriamine (DETA), on a copper-porphyrin-based metal–organic framework (Cu-TCPP). The strained 3% Cu-TCPP/CdSe-DETA (3% Cu-TCPP/CdSe-D) demonstrates a substantial enhancement in photocatalytic H2O2 production, reaching 2338.23 µmol g−1 h−1 under visible light, a 2.86-fold enhancement over unmodified CdSe-DETA. |
