基于生物分子多巴胺，开发了一种简单而通用的制备尺寸可控且单分散的亚微米碳球的策略。与传统的碳材料不同，所得到的碳亚微米球含有少得多的sp（3）碳和高水平的电活性氮。此外，金属-碳杂化亚微米球易于制备，在氧还原反应中显示出非常有前途的催化性能。
A simple, yet versatile strategy to prepare size-controlled and monodisperse carbon sub-micrometer spheres is developed based on the biomolecule dopamine. Unlike traditional carbon materials, the resulting carbon sub-micrometer spheres contain much less sp (3) carbon with high-level electroactive nitrogen. Moreover, metal-carbon hybrid sub-micrometer spheres can be easily obtained, and show highly promising catalytic properties in the oxygen-reduction reaction.
