Abstract

Ruthenium-based electrocatalysts have emerged as a promising alternative to iridium when it comes to the oxygen evolution reaction (OER), particularly in proton exchange membrane water electrolyzers (PEMWE). Although Ru-based catalysts exhibit superior intrinsic activity, their widespread adoption is hindered by stability challenges under acidic operating conditions, necessitating strategies to mitigate dissolution and degradation. This review offers an in-depth examination of Ru-based catalysts, highlighting the critical role of support materials in determining their catalytic activity, electronic conductivity, and long-term stability. The discussion is systematically organized according to the type of…
