JKJun Seop KimKorea Advanced Institute of Science and TechnologySLS.-H. LeeKorea Advanced Institute of Science and TechnologyDKDongho KimKorea Advanced Institute of Science and Technology

Key Points

  • The aim is to investigate how reducing RuO2 crystal size affects solute incorporation and solid-solution stability during acidic oxygen evolution.
  • Synthesis of RuO2 with crystal sizes below 10 nm
  • Evaluation of cation miscibility
  • Assessment of catalytic stability across 20 compositions
  • Reducing crystal size enhances cation miscibility in RuO2
  • Stable solid solutions were achieved in smaller crystal sizes
  • Systematic evaluation shows improved catalytic stability for acidic water oxidation

Abstract

Reducing RuO 2 crystal size below 10 nm enhances cation miscibility, allowing the synthesis of stable solid solutions and systematic evaluation of their catalytic stability for acidic water oxidation over 20 compositions.
