Abstract
A metal-free porphyrin based crystalline 2D organic polymer obtained from the condensation of terephthaloyl chloride and 5,10,15,20-tetrakis(4-aminophenyl porphyrin, namely HTAPP), which is an effective bifunctional electrocatalyst for the oxygen evolution reaction (OER) in basic conditions and the hydrogen evolution reaction (HER) in neutral solutions. The electrochemical response of this material is explored under oxidation and reduction conditions in order to study its catalytic activity, charge transfer and stability.
