Breakthrough in Nanotechnology: Enzymatic Modification of Covalent Organic Frameworks for Enhanced Photocatalysis

Strategic Insights -

Researchers at the Southern University of Science and Technology (SUSTech) have developed a novel enzymatic modification strategy for tailoring the structure and functionality of covalent organic frameworks (COFs). This groundbreaking approach enables the efficient incorporation of functional groups within COF pore channels, leading to enhanced photocatalytic hydrogen peroxide production. The research has been published in the Journal of the American Chemical Society.

The study bridges the gap between enzymatic catalysis and reticular materials engineering, offering a conceptual breakthrough in COF postsynthetic modification and functionalization. By leveraging enzymatic catalysis, the researchers achieved a high grafting efficiency under ambient aqueous conditions, resulting in a significant increase in photocatalytic activity. Theoretical calculations and in situ experiments revealed that the incorporation of specific functional groups promotes exciton dissociation, charge separation, and proton supply for hydrogenation intermediates, ultimately facilitating the photocatalytic production of hydrogen peroxide.
