While traditional trial-and-error methods and recent generative models have shown promise, they struggle to capture the intrinsic coupling between surface geometry and adsorbate interactions. To address this limitation, we propose CatFlow, a flow matching-based framework for de novo design and structure prediction of heterogeneous catalysts. Our model operates on a primitive cell-based factorized representation of the slab-adsorbate complex, reducing the numbe","authors_text":"Honghui Kim, Minkyu Kim, Nayoung Kim, Sungsoo Ahn","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-02-05T06:50:02Z","title":"CatFlow: Co-generation of Slab-Adsorbate Systems via Flow Matching"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2602.05372","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9e31cf3566232e8ea5eb556a75785dcc7bc6c61bd083b8c5a3ae4f3725d82c37","target":"record","created_at":"2026-05-20T00:04:24Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3106b798574ba20c849e69d5d946caac2cb3cecabc97687a7ce430030d99887e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-02-05T06:50:02Z","title_canon_sha256":"e0e78741ad041e12a54cc8f6bbca02b23ab96bf08b6b2e02eac1bb9d82e2deeb"},"schema_version":"1.0","source":{"id":"2602.05372","kind":"arxiv","version":2}},"canonical_sha256":"777fd59279145fb174c759d497aa52fb4483f506b508ffa713f1981a4c6e3c69","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"777fd59279145fb174c759d497aa52fb4483f506b508ffa713f1981a4c6e3c69","first_computed_at":"2026-05-20T00:04:24.561520Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:04:24.561520Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ya5fW9KzSL8lxSN2KllXK8iGWrurrtUubW7A+MOgQJ7OhBeNf4Ebjqkyh9k1UcJ0i7QSyGw/lRzdsyBx9lsmBA==","signature_status":"signed_v1","signed_at":"2026-05-20T00:04:24.562448Z","signed_message":"canonical_sha256_bytes"},"source_id":"2602.05372","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9e31cf3566232e8ea5eb556a75785dcc7bc6c61bd083b8c5a3ae4f3725d82c37","sha256:0caedcf19b069f3d1deae032bcc586f17d7256512b1cebdd788d48315427db3c"],"state_sha256":"4bf22dcfb93fd3179905e69d250a5c0abafc0b703b375198b3dff3a209385ce8"}
