Experiments were conducted in a high-pressure autoclave, with post-corrosion analysis including gas breakthrough tests, digital microscopy, and XPS. Results show that corrosion depth and rate increase with temperature. When temperature rose from 30 \u00b0C to 90 \u00b0C, the corrosion-related degradation extent of cement plugs increased from 15.2 mm to 31.6 mm, significantly higher than the increases for Sn-58Bi (0.35 to 0.65 mm) and Sn-65.7Bi-2.3Sb (0.11 to 0.29 mm). The degradation mechanisms of the two types of sealing materials were fundamentally different: class G cement plugs mainly experienced CO2-induced bulk degradation within the cement matrix, resulting in structural deterioration, whereas bismuth-based alloy plugs exhibited limited bulk corrosion and were primarily affected by localized degradation at the alloy\u2013casing interface. XPS identified (BiO)2CO3 as the primary corrosion product. Corrosion impaired sealing integrity: after 90 \u00b0C exposure, the breakthrough pressure of cement dropped by 73%, compared to only 2.4% for Sn-58Bi and 0.6% for Sn-65.7Bi-2.3Sb. The study concludes that corrosion accelerates with temperature in CO2-rich environments, and Sn-65.7Bi-2.3Sb exhibits superior corrosion resistance to Sn-58Bi, providing experimental insights into the corrosion resistance and sealing performance evolution of these alloys under simulated CCUS conditions.<\/jats:p>","DOI":"10.1021\/acsomega.6c03667","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T18:02:21Z","timestamp":1788890541000},"page":"55316-55326","source":"Crossref","is-referenced-by-count":0,"title":["Corrosion Resistance\nof Sn-58Bi and Sn-65.7Bi-2.3Sb\nLow-Melting Alloys in Simulated Geological CO2 Sequestration\nEnvironments"],"prefix":"10.1021","volume":"11","author":[{"given":"Gonghui","family":"Liu","sequence":"first","affiliation":[{"name":"Beijing University of Technology , , ,","place":["Beijing, China, 100124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengyang","family":"Jia","sequence":"additional","affiliation":[{"name":"Beijing University of Technology , , ,","place":["Beijing, China, 100124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4983-5220","authenticated-orcid":true,"given":"Chunqing","family":"Zha","sequence":"additional","affiliation":[{"name":"Beijing University of Technology , , ,","place":["Beijing, China, 100124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing University of Technology , , ,","place":["Beijing, China, 100124"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"2026092210565764900_cit1","first-page":"86","article-title":"Study on utilization and geological storage of CO2 in\nCCUS","volume":"42","author":"Li","year":"2022","journal-title":"Mod.
