- Abstract
- Here we report the fabrication of a novel three-dimensional conjugated porous polymer (CP-PP1) developed by a palladium-catalysed Sonogashira poly-condensation reaction. The solid polymer was thoroughly characterized by C-13 cross-polarization solid-state NMR and X-ray photoelectron spectroscopy (XPS). The pristine nitrogen-containing CPP was explored as an electrocatalyst for the oxygen reduction reaction (ORR) in alkaline media 0.1 M KOH. We observed that in the case of pristine polymer CPP-P1 oxygen reduction occurs through four electron transfer pathway with excellent stability and good tolerance to methanol. The detailed molecular-level structure for oxygen reduction and mode of oxygen binding site to the polymer was explained by density functional theory (DFT) calculation.
