Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • Electrides possess unique electron-rich structures beneficial for catalysis.
  • Challenges include instability and synthesis limitations in electrochemical applications.
  • Titanium oxide electrides offer potential but require optimized synthesis and characterization.

Purpose of the Study:

  • To develop a method for synthesizing phase-pure titanium oxide (Ti3O) electride nanoparticles.
  • To investigate the performance of Ti3O as a support for iridium (Ir) nanocatalysts in the oxygen evolution reaction (OER).
  • To explore the electronic structure engineering capabilities of electrides in electrocatalysis.

Main Methods:

  • Kinetically controlled gas-solid reaction for Ti3O electride nanoparticle synthesis.
  • Characterization of Ti3O electrical conductivity and electrochemical stability window.
  • Electrocatalytic testing of Ir/Ti3O catalysts for OER in acidic media using three-electrode cells and proton exchange membrane water electrolyzers.

Main Results:

  • Synthesized phase-pure Ti3O electride nanoparticles with high conductivity (617 S cm⁻¹) and a wide stability window (-0.4 to 2.1 V vs RHE).
  • Ti3O support induced strong metal-support interactions, preventing Ir nanoparticle amorphization and coalescence during OER.
  • Formation of subsurface oxygen-confined Ir nanoparticles, shifting the OER mechanism to adsorbate evolution mechanism (AEM) and enhancing activity and stability.

Conclusions:

  • Ti3O electrides are effective supports for Ir nanocatalysts, significantly improving OER performance.
  • The unique metal-support interactions and formation of novel active sites enable superior catalytic activity and stability.
  • Electrides represent a promising class of materials for advanced electrocatalyst design and stabilization of unique catalytic phases.
