AI Article Synopsis

  • A new, efficient metal-free N-doped carbon electrocatalyst was created using a one-pot pyrolysis method from a lone Zn(II)-MOF with a combination of azolate and terephthalate ligands.
  • The electrocatalyst showed impressive performance with an onset potential of 0.88 V (RHE) in a 0.1 M KOH solution and 0.79 V (RHE) in a 0.5 M HSO solution.
  • This work highlights the catalyst as one of the top-performing metal-free options for the acidic oxygen reduction reaction (ORR).

Article Abstract

A highly efficient metal-free N-doped carbon electrocatalyst toward oxygen reduction was obtained by one-pot pyrolysis of a single Zn(II)-MOF with mixed azolate and terephthalate ligands, demonstrating of 0.88 V ( RHE) in 0.1 M KOH, and 0.79 V ( RHE) in 0.5 M HSO. It represents one of the best metal-free N-doped carbon electrocatalysts for the acidic ORR.
