Structural advantage of keto-linked Fe-porphyrin polymer in boosting hydrogen evolution reaction

Abstract

Herein, we introduce Tp-FeTAPP synthesized from 2,4,6-triformylphloroglucinol (Tp) and iron-coordinated tetrakis(4-aminophenyl)porphyrin (FeTAPP), a non-precious metal catalyst for HER that surpasses existing HER catalysts. Its impressive HER performance, with a low overpotential of 140 mV, is attributed to optimized metal active sites, enhanced charge transfer, and efficient mass transport through its porous structure, ensuring both stability and sustainability.
