Introduction Recently, Professor Luis Echegoyen and colleagues from the University of Texas at El Paso reported two covalent organic frameworks (COFs) based on Co(II)-porphyrin/[2,1,3]-benzothiadiazole (BTD), Co@rhm-PorBTD and Co@sql-PorBTD, and utilized them for O2 electrocatalytic reduction (ORR). The results show that both COFs exhibit 5.8 times (Co@rhm-PorBTD) and 1.3 times (Co@sql-PorBTD) higher mass activity than commercial … Read more
