Porous carbon obtained by co-pyrolysis of plastic and biomass has received a lot of attention due to its excellent adsorption properties, and the pore structure plays an essential role in adsorption performance, however, the pore structure is still not well understood. Herein, we synthesized cyanobacteria-based porous carbon derived from cyanobacteria and polypropylene plastic by one-step method. CPC-800–30% exhibited a high BET surface area (2140 m²/g), pore volume up to 1.44 cm³/g. PP not only improved the pore structure of porous carbon, but also enriched the types of functional groups, such as O–H, N–H, C=O, and –CH, due to dehydroxylation or amino group decreased, resulting in the hydrogen radicals increased, hence PP had positive effect for biomass during co-pyrolysis. Meanwhile, CPC-800–30% showed excellent methylene blue (MB) adsorption capacity (667 mg/g). This work provided a new strategy for enhancing porous carbon structure via using PP as additive.

塑料与生物质共热解得到的多孔碳因其优异的吸附性能而受到广泛关注，而孔结构对吸附性能起着至关重要的作用，但孔结构仍不清楚。在此，我们通过一步法合成了源自蓝藻和聚丙烯塑料的蓝藻基多孔碳。CPC-800–30% 表现出高 BET 表面积 (2140 m ² /g)，孔体积高达 1.44 cm ³/G。PP不仅改善了多孔碳的孔结构，而且由于脱羟基或氨基减少，富集了O-H、N-H、C=O和-CH等官能团的类型，从而产生了氢自由基增加，因此 PP 在共热解过程中对生物质有积极影响。同时，CPC-800-30% 表现出优异的亚甲蓝 (MB) 吸附容量 (667 mg/g)。这项工作为通过使用 PP 作为添加剂增强多孔碳结构提供了一种新策略。
