沸石颗粒模板共碳化将工业 PTFE 废料转化为多孔碳纳米片用于电容储能
Scalable Upcycling of Industrial Waste Polytetrafluoroethylene Into Porous Carbon Nanosheets by Zeolite Particle Templates for Capacitive Energy Storage
AI 导读
研究提出沸石颗粒模板共碳化策略，将工业 PTFE 废料催化转化为分级多孔碳纳米片（PCN），同时把 81% 以上的氟固定为可回收 NaF。机理研究表明 ZSM-5 模板电子活化 C─F 键并降低脱氟能垒，驱动连续缩合的结构演化。
推荐理由
沸石颗粒模板共碳化把 PTFE 废料转化为多孔碳纳米片，并将 81% 以上的氟固定为可回收 NaF，为含氟废料回收提供了一条可放大的路线。
创新点
针对 PTFE 热解只排放氟碳、不生成固体碳骨架的问题，用 ZSM-5 颗粒模板电子活化 C─F 键、降低脱氟能垒，使废 PTFE 在共碳化中形成分级多孔碳纳米片，同时把氟以 NaF 形式回收。
