日本のGX文脈において
CCUS・炭素回収材料の基礎研究であり、SSBJ開示や国内政策への直接的な示唆は乏しい。ただし国内の産業廃棄物・農業残渣活用やカーボンリサイクル技術に関心を持つ読者には参考となる。
In the global GX context
This is a materials-science contribution to CCUS adsorbent development, relevant to the broader decarbonization toolkit but not directly tied to TCFD/ISSB/CSRD disclosure frameworks. It adds to global scholarship on low-cost biomass-derived sorbents for carbon capture.

📄 Abstract（原文）
ABSTRACT The efficient capture of greenhouse gases such as carbon dioxide (CO 2 ) and methane (CH 4 ) is of critical importance due to their substantial contributions to global warming. In this study, novel nitrogen‐doped porous carbons were synthesized from green and red plum ( Prunus domestica ) seeds via melamine‐assisted pyrolysis and systematically compared with nitrogen‐doped carbons derived from commercial activated carbon, graphene nanoplatelets, and multiwalled carbon nanotubes. Textural analyses revealed that the biomass‐derived carbons (NGPAC and NRPAC) exhibit exceptionally high surface areas (1759.9 and 1548.7 m 2 /g, respectively) and micropore‐dominated structures further enriched by nitrogen functionalities. Gas adsorption measurements at 298 K demonstrated that NGPAC and NRPAC achieved the highest CO 2 uptakes (3.9 mmol/g) and superior CH 4 capacities (1.37 and 1.15 mmol/g, respectively), significantly outperforming both commercial carbons (NAC) and nanocarbon‐based materials (NNT and NGR). Adsorption isotherm analyses indicated that the Langmuir and Freundlich models best described the equilibrium data, highlighting favorable adsorption on heterogeneous microporous surfaces. Kinetic studies showed that the pseudo‐first‐order model most accurately captured the adsorption behavior, with bio‐derived carbons displaying rapid uptake rates attributable to their accessible micropores and surface heteroatoms. Overall, these findings demonstrate that plum seed‐derived N‐doped carbons are highly efficient, sustainable, and low‐cost adsorbents for CO 2 and CH 4 capture. This work not only valorizes an underutilized agricultural byproduct as a promising precursor for advanced carbon materials, but also provides new insights into the role of precursor type and nitrogen functionalities in tailoring gas adsorption performance.
