Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • Conductive polymer hydrogels offer large surface areas and tunable properties.
  • Metal functionalization can enhance hydrogel performance for electrocatalysis.
  • Applications of metal-functionalized hydrogels in electrocatalysis remain underexplored.

Purpose of the Study:

  • To synthesize and investigate transition-metal-functionalized polyaniline-phytic acid (PANI-PA) hydrogels for electrocatalysis.
  • To evaluate the electrocatalytic activity of these hydrogels for the oxygen evolution reaction (OER).
  • To develop efficient and sustainable OER electrocatalysts and electrodes.

Main Methods:

  • Synthesis of transition-metal-functionalized PANI-PA hydrogels.
  • Incorporation of iron (Fe) and cobalt (Co) into the hydrogel matrix.
  • Fabrication of free-standing electrodes using nickel foam or carbon cloth.

Main Results:

  • Fe-functionalized PANI-PA hydrogels showed high affinity for Fe.
  • Hydrogels containing both Fe and Co exhibited the most effective OER electrocatalysis.
  • The optimized NF@Hgel-Fe0.3Co0.1 hydrogel required only 280 mV overpotential for OER at 10 mA cm-2 in 1 M KOH.
  • Metal-functionalized hydrogels were successfully fabricated into free-standing electrodes.

Conclusions:

  • Facile synthesis of efficient and sustainable OER electrocatalysts based on metal-functionalized hydrogels.
  • Demonstrated potential of PANI-PA hydrogels functionalized with earth-abundant transition metals for electrocatalysis.
  • Developed a simple method for creating high-performance, free-standing electrocatalytic electrodes.
