Abstract High‐entropy alloy nanowires (HEA NWs) hold significant promise for achieving exceptional catalytic activity and stability, owing to their unique 1D morphology the electronic engineering potential of HEAs. However, controlled synthesis HEA NWs remains a challenge. In this work, novel wet‐chemical approach is reported ultrathin NWs, represented by PtRuNiCuPb, through an active‐hydrogen (H·)‐mediated reduction mechanism. The H· species, generated organic dehydrogenation, facilitate effective co‐reduction metal salts with differing potentials, while mild conditions ensure control toward nanowire formation. resulting PtRuNiCuPb exhibit remarkable in electrocatalytic hydrogen oxidation reaction (HOR) alkaline media, due multimetallic compositions abundant grain boundaries. At 50 mV, specific mass activities reach 8.46 mA cm −2 5.54 A mg Pt+Ru −1 , respectively, ≈11.3 14.5 times greater than those commercial Pt/C. Thanks morphology, demonstrate excellent retaining 97% initial after 20000 cycles accelerated durability testing. These findings offer promising strategy designing highly efficient durable catalysts using morphologies applications.

Electrochemical conversion has been regarded as an ideal technology for achieving clean and sustainable energy, showing significant promise in addressing the increasingly serious energy crisis environmental pollution. Ru-containing electrocatalysts (RUCE) outperform other precious metals due to elevated intrinsic activity superior cost-effectiveness, developing into a promising candidate electrochemical reactions. A challenge field of catalyst discovery lies its heavy reliance on empirical methods, rather than approaches that are rooted rational design principles. This review first concentrates catalytically active sites critical factors governing catalytic performance durability. Then, comprehensive summary multifunctional modification strategies ranging from nanoscale atomic scale is explored control structure improve performance. By unveiling roles each component modified RUCE at level, their identified discussed establish structure-performance relationship catalysts. Finally, challenges perspectives Ru-based materials hydrogen, oxygen, nitrogen reactions presented inspire further efforts toward understanding meet ever-growing demand future.
