摘要
双连续多孔材料具有三维相互连接的网络和孔道,可促进质量向材料内部扩散。然而,要轻松构建这种复杂而精细的结构仍具有挑战性。本文报告了一种胺介导的聚合诱导熔融组装策略,用于合成具有各种孔结构的多酚基双连续多孔球。具体来说,通过 TEM 观察到的孔隙生成模板的融合促进了双连续多孔网络的发展,并通过三维重建得到了证实。此外,热解后产生的双连续多孔碳颗粒直径≈600 nm,可触及表面积高达 359 m2 g-1,孔径为 40-150 nm,在水污染中催化降解磺胺甲基嘧啶的性能有所提高。本研究拓展了界面张力-溶剂依赖性多孔球的工具箱,同时为了解其结构-性能关系提供了新的视角。
Polyphenol-Based Bicontinuous Porous Spheres Via Amine-Mediated Polymerization-Induced Fusion Assembly.
Bicontinuous porous materials, which possess 3D interconnected network and pore channels facilitating the mass diffusion to the interior of materials, have demonstrated their promising potentials in a large variety of research fields. However, facile construction of such complex and delicate structures is still challenging. Here, an amine-mediated polymerization-induced fusion assembly strategy is reported for synthesizing polyphenol-based bicontinuous porous spheres with various pore structures. Specifically, the fusion of pore-generating template observed by TEM promotes the development of bicontinuous porous networks that are confirmed by 3D reconstruction. Furthermore, the resultant bicontinuous porous carbon particles after pyrolysis, with a diameter of ≈600 nm, a high accessible surface area of 359 m2 g-1, and a large pore size of 40-150 nm manifest enhanced performance toward the catalytic degradation of sulfamethazine in water decontamination. The present study expands the toolbox of interfacial tension-solvent-dependent porous spheres while providing new insight into their structure-property relationships.
