Abstract Green hydrogen holds immense promise in combating climate change and building a sustainable future. Owing to its high power‐to‐gas conversion efficiency, compact structure, fast response, the proton exchange membrane water electrolyzer (PEMWE) stands out as most viable option for widespread production of green hydrogen. However, harsh operating conditions PEMWE make it heavily dependent on noble metal‐based catalysts (NMCs) incur operational maintenance costs, which hinder extensive adoption. Hence, is imperative improve performance lifespan NMCs develop advanced components reduce overall costs integrating technology into practical applications. In light this, fundamental design principles employed acidic electrolysis are summarized, well recent advancements compositional structural engineering enhance intrinsic activity active site density. Moreover, innovations stack their impact cost‐benefit presented. Finally, current challenges examined, potential solutions optimizing electrocatalytic discussed.

Ruthenium oxide (RuO2), due to its comparable binding energy with *H and cost-effectiveness against Pt, has emerged as a pivotal electrocatalyst for oxygen evolution reaction (OER). In the present study, RuO2 nanocrystals (NCs) nanowires (NWs) were obtained by molten salt process morphology, crystal structure, local bonding features examined using electron microscopy X-ray absorption spectroscopy. From electrochemical measurement, both NCs NWs exhibit favorable stability activity toward in an alkali medium, althought higher activity, which is likely attributed larger surface area high structural disorder. The theoretical calculation reveals that primary (110) orientation show overpotential d-band center's proximity Fermi level versus (101). work suggests could be efficient method producing metal catalysts tailorable geometry performances.
