Abstract

A nitrogen-doped hierarchical porous carbon (MPC-N) was synthesized from polyethylene terephthalate (PET) fiber waste via a facile and eco-friendly strategy. PET fibers were pretreated with sodium hydroxide (NaOH)-ethanol solution containing tris(2-aminoethyl)amine (TAEA) to form a carbon precursor, followed by pyrolysis at 700 °C under N₂. The resulting MPC-N exhibited a high specific surface area (427.01 m²/g) and abundant nitrogen/oxygen functional groups, enabling efficient activation of peroxydisulfate (PS) for rapid degradation of bisphenol A (BPA). In the MPC-N/PS system, 20 mg/L BPA was completely degraded within 10 min, with minimal interference from inorganic ions or natural organic matter. This work provides a dual solution to plastic waste recycling and organic pollutant remediation.

从PET纤维废料中提取一种新型n掺杂多孔碳，用于高效过硫酸盐活化降解双酚A

以聚对苯二甲酸乙二醇酯（PET）纤维废料为原料，采用简单、环保的方法合成了氮掺杂分层多孔碳（MPC-N）。采用含三（2-氨基乙基）胺（TAEA）的氢氧化钠(NaOH)-乙醇溶液对PET纤维进行预处理，形成碳前驱体，在700℃N2下热解。得到的MPC-N具有高比表面积（427.01 m2/g）和丰富的氮/氧官能团，能够有效激活过硫酸氢盐（PS），快速降解双酚a （BPA）。在MPC-N/PS体系中，20 mg/L的BPA在10 min内被完全降解，无机离子和天然有机物的干扰最小。本研究为塑料废弃物回收利用和有机污染物修复提供了双重解决方案。
