Co phthalocyanine covalent organic frameworks with enhanced π-electron delocalization for boosted electrocatalytic CO2 reduction reaction

By connecting Co phthalocyanine with 1,2,4,5-benzenetetramine (BTM) or 3,3’-diaminobenzidine (DAB), two covalent organic frameworks (CoPc-BTM-COF and CoPc-DAB-COF) with tuned π-delocalization features are synthesized for electrocatalytic CO2 reduction. CoPc-BTM-COF is more...
