Overview

Experimental study demonstrates efficient alkaline oxygen evolution using ultra-low nickel loadings in ceramic fibre mats, indicating viable pathways for cost-effective water electrolysis.

Key Points

  • To investigate the electrocatalytic performance of polymer-derived silicon carbo(xy)nitride fibre mats anchored with ultra-low amounts of iron or nickel toward the alkaline oxygen evolution reaction.
  • Synthesized porous, interconnected SiCN(O) fibre mats incorporating Fe or Ni via the polymer-derived ceramics route.
  • Characterized material morphology, nanocrystal formation (Fe3C and metallic Ni), and nitrogen binding modes using spectroscopy and microscopy.
  • Evaluated electrocatalytic oxygen evolution reaction activity in 1 M KOH alkaline electrolyte.
  • Ni-SiCN(O) fibre mats achieved an overpotential of 460 mV at 10 mA cm⁻² in 1 M KOH with an ultra-low nickel loading of 0.01 mg cm⁻².
  • Fe-SiCN(O) exhibited substantially lower electrocatalytic activity than the nickel counterpart, attributed to the formation of Fe3C and the absence of active Fe-Nx coordination sites.
