Local structure, chemistry, and lattice strain variation can affect electrocatalytic activity. We investigate the effect of Ru content on defect formation and electrochemistry in Au\u2010Pd\u2010Pt\u2010Ru CCSS thin films. A thin\u2010film material library covering a wide composition range was fabricated by room\u2010temperature combinatorial co\u2010sputtering. High\u2010throughput characterization, including electron microscopy, X\u2010ray diffraction, and electrochemical screening, were used to correlate composition and microstructural features with catalytic activity.

The samples exhibit face\u2010centered cubic crystal structures, with lattice contraction occurring and a transition from a high density of nanotwins to high\u2010density stacking faults with increasing Ru content. These planar defects could influence electrocatalytic activity when they terminate at surfaces. Moreover, the hydrogen evolution reaction activity improves with higher Ru content, suggesting that Ru can tune the surface energy for hydrogen adsorption through interactions with neighboring atoms. Atom probe tomography reveals local compositional fluctuations at grain boundaries depending on the Ru content. The findings provide a new insight into surface atom arrangement design in the CCSS electrocatalysts with enhanced performance.\n
