recommendations! Published in 2022 at "Advanced Materials"

DOI: 10.1002/adma.202203139

Abstract: Covalent organic frameworks (COFs) have been applied as potential electrocatalysts for CO2 reduction reaction (CO2RR) due to their adjustable architecture and porous feature. Herein, tetraanhydrides of 2,3,9,10,16,17,23,24‐octacarboxyphthalocyanine cobalt(II) (CoTAPc) are used as nodes to couple… read more here.
