AI Technical Summary

Technical Problem

Existing photocatalytic materials suffer from low efficiency and poor stability in the preparation of hydrogen peroxide (H2O2), rely on energy-intensive and environmentally harmful industrial processes, and pose safety risks during storage and transportation. Furthermore, the homogeneity of molecular structures limits performance breakthroughs.

Method used

Using porous squaric acid-phenylenediamine polymer as a photocatalyst, a Schiff base polymer is formed through a solvothermal reaction. By utilizing the isomerization engineering of ortho- and meta-phenylenediamine to control the separation of electrons and holes, the light absorption range is broadened to the infrared region, thus realizing visible light photocatalytic H2O2 generation without sacrificial agents.

Benefits of technology

It significantly improves the H2O2 generation efficiency to 8515.0 μmol g-1h-1, possesses efficient, stable and safe photocatalytic performance, and has the ability to sterilize and remove pollutants, making it suitable for different water quality and pH conditions.
