本研究は、サトウキビバガスとココナッツ殻を様々な比率で混合し、低KOH含浸（0.1:1）で共炭化して活性炭を調製した。バガス-rich試料は高い表面積（576 m2/g）とミクロ細孔容積を示し、ココナッツ-rich試料はカルボキシル基が多かった。メチレンブルー吸着試験では、混合試料が単一前駆体より優れた吸着能を示し、廃棄物の持続可能な活用と薬品使用削減に寄与する。
English
This study prepared activated carbons by co-carbonizing sugarcane bagasse and coconut shell blends with low KOH impregnation (0.1:1). The bagasse-rich sample showed high surface area (576 m2/g) and micropore volume, while the coconut-rich sample had more carboxylic groups. Methylene blue adsorption tests showed that blended samples outperformed single-precursor analogues, offering a sustainable route for waste valorization with reduced chemical use.

📄 Abstract（原文）
Co-carbonizing agricultural residues represents an efficient strategy to tailor activated carbon properties while reducing chemical activating agents. In this work, activated carbons (ACs) were prepared by blending sugarcane bagasse and coconut shell at different mass ratios, followed by pre-carbonization at 350 °C, KOH impregnation at a low mass ratio of 0.1:1 (w/w), and activation at 600°C. Characterization via Boehm titration, pHpzc, iodine number, and methylene blue number revealed that the precursor ratio influences both structural and chemical properties. Specifically, the bagasse-rich blend (CA-B80) showed the highest estimated specific surface area (576 m2.g-1) and micropore volume (0.382 cm3.g-1) among the samples, pointing to a positive textural effect during co-carbonization. Conversely, the coconut-rich blend (CA-B20) presented the highest concentration of carboxylic groups (1.31 mmol.g-1), suggesting a distinct trend in surface chemistry enhancement. In batch adsorption tests, CA-B50 and CA-B20 achieved methylene blue uptake capacities of 492 and 477 mg.g-1, respectively, outperforming single-precursor analogues. These findings demonstrate that co-carbonization provides a sustainable and cost-effective route to valorize tropical biomass wastes with minimal chemical demand.
