AI Technical Summary
Existing photocatalytic materials are inefficient in preparing H2O2, and traditional methods are costly and pollute the environment. Existing inorganic materials have a narrow light absorption range and low solar energy utilization, while organic polymers lack specific redox centers.
Design a azirquinone-based polymer material to construct a polymer with precise band structure and active center through the coupling reaction of azirquinone and electron-rich compounds. Utilize the two-electron redox properties of azirquinone to promote the reduction of O2 and the oxidation of H2O to H2O2.
It achieves efficient H2O2 production from H2O and O2 under ambient temperature and pressure and visible light excitation, improving the utilization efficiency of photogenerated electrons and holes, enhancing photocatalytic reaction efficiency, and reducing production costs.
