In this work, cross\u2010dimensional coupled atomic\u2010scale structural degradation mechanism of representative compound PtZn nanoalloy during oxygen reduction reaction electrocatalysis was comprehensively interrogated by integrating the atomic electron tomography (AET), synchrotron x\u2010ray techniques, and theoretical calculations. In situ x\u2010ray measurements demonstrated a globally stable face\u2010centered tetragonal bulk structure during continuous cycling; at the real three\u2010dimensional atomic level, further AET observations revealed significant localized surface degradation characterized by inhomogeneous Pt segregation, lattice transition, bond length expansion, coordination number reduction, and increased normal strain. These synergistic experimental results demonstrate a phenomenon of inhomogeneous structure degradation, revealing how dynamic interfacial change and bulk lattice stability propagate localized compositional heterogeneity: significant guidance to synthesize defect\u2010tolerant Pt skin against Zn dissolution. Corroborated by theoretical calculations, our findings established that the Pt segregation and structural transformation on the surface and sub\u2010surface of the catalyst were the energy\u2010driven degradation pathways and played important roles in the sustained deactivation of the catalyst. By integration of cross\u2010dimensional information, we link surface atomic heterogeneity on the surface of individual particles, overall structural changes of the catalyst and catalytic performance.<\/jats:p>","DOI":"10.1002\/anie.8710156","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T06:38:37Z","timestamp":1791355117000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cross\u2010Dimensional Coupled Atomic Insights Into Structural Degradation of Pt\u2010Alloy Oxygen Reduction Reaction Catalysts"],"prefix":"10.1002","author":[{"given":"Shiqiang","family":"Feng","sequence":"first","affiliation":[{"name":"State Key Laboratory of Structural Chemistry Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences  Fuzhou China"},{"name":"Fujian Science &amp;
