本研究では、未分画・未化学修飾のソフトウッドクラフトリグニンと酢酸セルロースから電界紡糸によりナノファイバーを作製。リグニン含有率80%まで可能。炭化後、水中のメチレンブルー吸着（19 mg/g）とCO2回収（2.2 mmol/g）の逐次利用を実証。CO2回収専用では3.1-3.9 mmol/gの吸着能を示し、リグニン含有率が低いほど高性能。資源効率と持続可能な材料設計に貢献。
English
This study fabricates electrospun nanofibers from unfractionated softwood kraft lignin and cellulose acetate (up to 80% lignin). After carbonization, they achieve sequential dye adsorption (methylene blue, 19 mg/g) and CO2 capture (2.2 mmol/g). For dedicated CO2 capture, sorption capacities range 3.1-3.9 mmol/g, higher with lower lignin content. This demonstrates a stepwise valorization of industrial lignin for water purification and carbon capture.

📄 Abstract（原文）
The development of bio‐based materials capable of addressing multiple environmental challenges is critical for advancing sustainable materials design. Herein, we report electrospun nanofibers from unfractionated, chemically unmodified softwood kraft lignin and cellulose acetate, where cellulose acetate acts as a carrier polymer, enabling the formation of uniform precursor fibers with lignin contents of up to 80%. The resulting nanofibers enable sequential dye adsorption from water (methylene blue removal capacity of 19 mg/g) and carbon dioxide (CO 2 ) capture (2.2 mmol/g) after carbonization. When evaluated solely for CO 2 capture, the pristine carbonized materials show sorption capacities of 3.1–3.9 mmol/g, which increase as lignin content in the precursor fibers decreases, underscoring the importance of tuning carbon yield and capture performance. The sequential utilization of a single precursor material demonstrates a stepwise transformation that aligns with resource efficiency and sustainable material design. Overall, this study demonstrates a viable route for the direct valorization of industrial lignin into functional materials for both water purification and carbon capture applications.
