Here, we designed a novel core\u2010shell electrocatalyst, PtPbSn\/Pt@sub\u2010SnO\n                    <jats:sub>x<\/jats:sub>\n                    , which combines a Sn\u2010modified PtPb intermetallic core, a tensile\u2010strained Pt shell, and a sub\u2010monolayer of SnO\n                    <jats:sub>x<\/jats:sub>\n                    . This architecture was achieved via a facile one\u2010pot synthesis. The introduced Sn is key to simultaneously inducing core lattice expansion, Pt\u2010shell tensile strain, and surface oxophilic sites. For the methanol oxidation reaction, it exhibits a mass activity of \u223c6.77 A mg\n                    <jats:sup>\u22121<\/jats:sup>\n                    <jats:sub>Pt<\/jats:sub>\n                    , outperforming PtPb and commercial Pt\/C. It also demonstrates exceptional long\u2010term stability over 80\u00a0000 s and high CO tolerance, alongside promising activity for ethanol and ethylene glycol oxidation. Density functional theory calculations reveal that the synergy between the tensile\u2010strained Pt shell and surface SnO\n                    <jats:sub>x<\/jats:sub>\n                    species optimizes the electronic structure of Pt. This optimization leads to enhanced adsorption of CH\n                    <jats:sub>3<\/jats:sub>\n                    OH and OH, weakened CO binding, and consequently, lowered energy barriers for the key steps. This work demonstrates that the synergistic design of a stable intermetallic core, a strained metal shell, and surface oxophilic species is an effective strategy for developing high\u2010performance and durable electrocatalysts for DAFCs.\n                  <\/jats:p>","DOI":"10.1002\/smll.74214","type":"journal-article","created":{"date-parts":[[2026,6,17]],"date-time":"2026-06-17T19:21:57Z","timestamp":1781724117000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Synergistic Integration of Tensile\u2010Strained Pt Shell and SnO\n                    <sub>x<\/sub>\n                    Sites in a Core\u2013Shell Nanocatalyst for Dual Enhancement of Methanol Oxidation Activity and Durability"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7828-5120","authenticated-orcid":false,"given":"Guangxia","family":"Wang","sequence":"first","affiliation":[{"name":"School of Applied Physics and Materials Wuyi University  Jiangmen P.
