Tunable Axial Symmetry β-ketoamine Covalent Organic Frame-works for Efficient Photocatalytic H 2 O 2 Synthesis in Seawater

JCJinyang ChenJZJie ZHOUNLNa Li

Key Points

  • This research aims to improve the photocatalytic production of hydrogen peroxide from seawater using covalent organic frameworks.
  • Developed tunable β-ketoamine covalent organic frameworks (COFs) for photocatalysis.
  • Tested the COFs under solar irradiation in seawater conditions.
  • Analyzed charge transport and catalyst stability during H2O2 synthesis.
  • Achieved significant H2O2 production rates using the new COFs.
  • Demonstrated enhanced charge transport compared to previous materials.
  • Noted reduced catalyst degradation over extended use in seawater.

Abstract

Photocatalytic production of hydrogen peroxide (H 2 O 2 ) from seawater represents a sustainable approach for solar energy conversion. However, complex ionic composition hinders charge transport and accelerate catalyst degradation, undermining efficiency and...
