Lignin has already sequestered biogenic carbon incorporated in its structure (i.e., atmospheric CO2 is captured during photosynthesis and plant growth). When extracted from wood through environmentally benign ways (e.g., using the polyethylene glycol (PEG) solvolysis process developed in our laboratory at FFPRI), lignin can be considered a superior starting material compared to petroleum-based analogues in respect to CO2 footprint. Furthermore, lignin is attractive for the synthesis of carbon materials, as it already has a polyaromatic structure, thus higher conversion yields can be realized compared to other biomass components (like cellulose).\r\nWe fabricated a unique large-pore mesoporous carbon from a PEG-grafted technical lignin (coined as glycol lignin). This material showed an exceptional CO2 capture-and-release profile due to capillary condensation in large mesopores close to the saturation pressure (3.2 MPa) at 270 K. On account of this phenomenon, a more energy-efficient pressure-swing regeneration process can be realized compared to a benchmark nanoporous (activated) carbon. Large-pore mesoporous carbons are considered those that have pores larger than 10 nm, thus cannot be fabricated using conventional soft-templating methods based on Pluronic® surfactants. In this presentation, we will share our latest results on our ongoing efforts in developing a new family of CO2 capture materials based on the nanoconfinement-induced capillary condensation phenomenon, offering energy-efficient, cost effective regeneration options.\r\n" description_type: abstract lang: eng ## Creator - name: SZABO Laszlo role: author organization: Center for Advanced Materials, Forestry and Forest Products Research Institute - name: Mizuki Inoue role: author orcid: https://orcid.org/0000-0003-3098-5448 organization: National Institute for Materials Science department: Research Center for Macromolecules and Biomaterials/Macromolecules Field/Polymer Process Technology Team - name: Yurina Sekine role: author organization: Center for Advanced Materials, Forestry and Forest Products Research Institute - name: Ryuhei Motokawa role: author organization: Japan Atomic Energy Agency - name: Yusuke Matsumoto role: author organization: Center for Advanced Materials, Forestry and Forest Products Research Institute - name: Thi Thi Nge role: author organization: Center for Advanced Materials, Forestry and Forest Products Research Institute - name: Edhuan Ismail role: author orcid: https://orcid.org/0000-0003-1031-6562 organization: National Institute for Materials Science department: Research Center for Macromolecules and Biomaterials/Macromolecules Field/Polymer Process Technology Team - name: Izumi Ichinose role: author orcid: https://orcid.org/0000-0002-2236-0942 organization: National Institute for Materials Science department: Research Center for Macromolecules and Biomaterials - name: Tatsuhiko Yamada role: author organization: Center for Advanced Materials, Forestry and Forest Products Research Institute ## Contact agent ## Publisher ## Managing organization ## Keyword - subject: lignin schema: not_defined - subject: mesoporous carbon schema: not_defined - subject: CO2 reocovery schema: not_defined ## Rights - identifier: http://rightsstatements.org/vocab/InC/1.0/ ## Other identifier(s) ## Data origin - data_origin_type: other ## Embargo start_date: 2025-07-10 end_date: 2026-01-10 ## Journal ## Conference name: The 19th Pacific Polymer Conference (PPC19) start_date: 2025-07-06 end_date: 2025-07-10 identifier: https://main.spsj.or.jp/ppc19/ ## Related item ## Funding ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen ## Chemical composition ## Structure for specimen ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software ## Custom property ## Fileset - id: 5b7a007e-f237-4edb-8b49-2acc076d8a8b filename: Abstract_PPC19_LaszloSzabo.doc content_type: application/msword size: 2731008 md5: e14dc485ab944d7d221a75dbfdfb7315 ## Thumbnail fileset_id: 5b7a007e-f237-4edb-8b49-2acc076d8a8b filename: Abstract_PPC19_LaszloSzabo.doc
