2D Salphen-based heteropore covalent organic frameworks for highly efficient electrocatalytic water oxidation

The construction of heteroporous covalent organic frameworks (COFs) is still a challenge. Herein, a series of 2D COFs with hexagonal and quadrilateral pores were constructed via in situ salphen or metal salphen formation. Metallized salphen-based COFs can be used as electrocatalysts towards water oxidation with an overpotential of 266 mV at 10 mA cm(-2).

Automated summary

The study successfully constructed a series of 2D COFs with hexagonal and quadrilateral pores, and found that metallized salphen-based COFs can be used as electrocatalysts for water oxidation.
