Abstract
Electrides, with their unique electron-rich architectures, hold transformative potential for catalysis but face critical challenges in electrochemical systems due to inherent instability and synthesis limitations. Here, we present a kinetically controlled gas–solid reaction to synthesize phase-pure Ti3O electride nanoparticles, which exhibit high electrical conductivity (617 S cm–1) and broad electrochemical stability window (−0.4 to 2.1 V vs RHE) in acidic media. When used as a support for iridium (Ir) nanocatalysts in the oxygen evolution reaction (OER), the Ti3O electride demonstrates strong metal–support interactions. These interactions suppress both amorphization and coalescence of the Ir nanoparticles…
