Abstract

Abstract Strain engineering is a powerful approach to tailoring the performance of metal electrocatalysts. Despite substantial advancements in controlling the average surface strain and establishing its correlation with catalytic activity, the impact of strain at individual active sites remains elusive. Here, we demonstrate the influence of site-specific strain on catalytic reactivity in Pt nanoclusters by quantitatively modulating and mapping the atomic-scale strain. We reveal a volcano-shaped relationship between eigenstrain─a descriptor of local anisotropic strain states─and intrinsic activity, confirmed through hydrogen electrocatalysis on Pt nanoclusters. Specifically, Pt atoms with optimal eigenstrain exhibit up to 2 orders of magnitude higher activity than strain-free sites, arising from electronic structure modification by inhomogeneous strain fields. These findings provide a quantitative framework for understanding site-specific strain phenomena and guide the rational design of strain-optimized metal catalysts.

Heuristic review

Dimension	Level	Weight	What that level means
Leverage	███░░ 3	16%	A method or resource many groups across the field will adopt within a year.
Magnitude	███░░ 3	20%	Large gain: roughly 2x, or a clear new state of the art on a hard, unsaturated problem.
Evidence	███░░ 3	20%	Solid: multiple benchmarks or cohorts, ablations, fair baselines, released code or data.
Novelty	███░░ 3	10%	A genuinely new approach to an open problem.
Trajectory	███░░ 3	14%	A clear path to scale.
Stakes	██░░░ 2	20%	Benefits a professional community (practitioners, clinicians, engineers).

Editor’s rationale

Heuristic triage from title and abstract text only, not a reading of the paper. Cues found: method (we report); gains (orders of magnitude); novelty (discovery); verification (independent replication); scale (scalable, orders of magnitude, efficient).
