Nitrogen-doped mesoporous carbon nanosphere (NMCS) with tunable sizes and uniform mesoporosity was synthesized by a facile soft-templating method. During the synthesis, F127 (PEO-PPO-PEO triblock copolymer) could be used not only as a soft template to generate the mesostructure but also as a size-control agent to tailor the size of NMCS in a relatively wide range of 100 to 700 nm. In addition, the synthesis process was simple and suitable for large-scale production. Moreover, the NMCS was used as support of ultrafine Ru nanoparticles (Ru/NMCS), which exhibited good catalytic performances for selective hydrogenation of quinolones. It is expected that the simple synthetic strategy for the NMCS can generate extensive interest in many catalysis and sorption applications.
通过简便的软模板法合成了尺寸可调且介孔均匀的氮掺杂介孔碳纳米球（NMCS）。在合成过程中，F127（聚环氧乙烷-聚环氧丙烷-聚环氧乙烷三嵌段共聚物）不仅可作为生成介观结构的软模板，还可作为尺寸控制剂，在100至700 nm的较宽范围内调整NMCS的尺寸。此外，合成过程简单且适合大规模生产。而且，NMCS用作超细钌纳米颗粒（Ru/NMCS）的载体，其对喹诺酮类的选择性氢化表现出良好的催化性能。预计NMCS的这种简单合成策略会在许多催化和吸附应用中引起广泛关注。
