A facile templated synthesis of functional nanocarbon materials with well-defined spherical mesopores is developed using all-organic porogenic precursors comprised of hairy nanoparticles with nitrogen-rich polyacrylonitrile shells grafted from sacrificial cross-linked poly(methyl methacrylate) cores (xPMMA-g-PAN). Such shape-persistent all-organic nanostructured precursors, prepared using atom transfer radical polymerization (ATRP), assure robust formation of template nanostructures with continuous PAN precursor matrix over wide range of compositions, and allow for removal of the sacrificial template through simple thermal decomposition. Carbon materials prepared using this method combine nitrogen enrichment with hierarchical nanostructure comprised of microporous carbon matrix interspersed with mesopores originating from sacrificial xPMMA cores, and thus perform well as CO2 adsorbents and as supercapacitor electrodes.
采用由具有富氮的聚丙烯腈壳的牺牲交联聚甲基丙烯酸甲酯核（xPMMA-g-PAN）接枝的毛发状纳米粒子组成的全有机孔形成前体制备功能纳米碳材料的简便模板合成，具有定义良好的球形介孔。这种形状保持的全有机纳米结构前体是使用原子转移自由基聚合（ATRP）制备的，可确保在宽组成范围内形成具有连续 PAN 前体基质的模板纳米结构，并允许通过简单的热分解去除牺牲模板。使用该方法制备的碳材料将氮富集与由源自牺牲 xPMMA 核的介孔组成的微孔碳基质的分级纳米结构相结合，因此作为 CO2 吸附剂和超级电容器电极表现良好。
