The many top-layer and subsurface arrangements of PtM alloys, however, create a local-motif space that is costly to enumerate with density functional theory (DFT). We develop a mechanism-informed, graph-assisted active-learning framework for adsorption-descriptor-based prioritization of CO-tolerance-relevant PtM motifs. A curated DFT dataset contains CO@Pt, OH@Pt, and OH@M adsorption energies. Interpretable element\u2013motif descriptors reveal target-dependent behavior: Pt-site adsorption depends on coupled local-environment effects, whereas OH@M is strongly metal-specific. Under identical structure-grouped validation, descriptor-guided MEGNet-style, SchNet, and DimeNet++ encoders were compared on bare-surface graphs. The MEGNet-style encoder gave the most faithful standalone motif representation, with an auxiliary-descriptor reconstruction mean absolute error of 0.048 and a motif-family accuracy of 0.998, while its descriptor\u2013latent Gaussian-process model matched DimeNet++ for Pt-site adsorption at substantially lower complexity. Retrospective uncertainty-aware and multi-objective acquisition accelerated the recovery of high-ranked motifs. Mo-containing families dominated the three-descriptor-qualified set; representative CO@M calculations showed that Ru- and Fe-containing motifs favor CO adsorption at M, whereas validated Mo-containing motifs retained a strong OH preference for M with nearly degenerate Pt\/M CO adsorption. The workflow, therefore, provides interpretable, small-data-compatible motif prioritization before full MOR pathway, kinetic, and electrochemical validation.<\/jats:p>","DOI":"10.1063\/5.0349556","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T12:23:30Z","timestamp":1788265410000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Mechanism-informed graph-assisted screening of PtM local motifs for CO-tolerant methanol oxidation"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-7431-2239","authenticated-orcid":false,"given":"Xiaohui","family":"Huang","sequence":"first","affiliation":[{"name":"College of Physics, Sichuan University 1 , Chengdu 610065,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9332-1203","authenticated-orcid":false,"given":"Hong","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Physics, Sichuan University 1 , Chengdu 610065,","place":["China"]},{"name":"Key Laboratory of High Energy Density Physics and Technology of Ministry of Education, Sichuan University 2 , Chengdu 610065,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,9,1]]},"reference":[{"key":"2026090108222209300_c1","doi-asserted-by":"publisher","first-page":"100054","DOI":"10.1016\/j.enrev.2023.100054","volume":"3","year":"2024","journal-title":"Energy Rev."},{"key":"2026090108222209300_c2","doi-asserted-by":"publisher","first-page":"20826","DOI":"10.1002\/anie.202004301","volume":"59","year":"2020","journal-title":"Angew.
