Robust mesoporous two-dimensional covalent organic frameworks enabled by biphenyl-porphyrin for accelerated CO2 electroreduction.
Covalent organic frameworks (COFs) incorporating metalloporphyrin units have gained significant attention as electrocatalysts for CO2 reduction. However, conventional phenylporphyrin-based COFs are fundamentally limited by narrow pore sizes (<3 nm), which impose severe mass transfer resistance and impede catalytic turn...
