Carbon nanospheres and their derived superstructures have attracted increasing attention due to their widespread applications ranging from electrochemistry to catalysis. However, it remains a great challenge to achieve mass production of biomass-derived monodisperse carbon nanospheres with a diameter <400 nm and their derived superstructures with a controlled size. Here, monodisperse and uniform nanospheres ranging from 120 to 360 nm were synthesized with the introduction of a small amount of poly(4-styrenesulfonic acid-co-maleic acid) sodium salt (PSSMA) to the hydrothermal system. In addition, spherical superstructures constructed of nanospheres with an adjustable size from 1.4 to 5.2 μm were fabricated in the presence of both PSSMA and hydrochloric acid. Moreover, carbonized carbon superstructures showed good performance as supports for catalytic hydrogenation. These findings may open up a new avenue for designing increasingly complex functional biomass-derived materials.

单分散碳纳米球及其衍生超结构的可持续和可扩展合成

碳纳米球及其衍生的超结构由于从电化学到催化的广泛应用而引起了越来越多的关注。然而,实现大规模生产直径<400 nm的生物质衍生的单分散碳纳米球及其尺寸受控的超结构仍然是一个巨大的挑战。在此,单分散和均匀的纳米球范围从120至360nm与引入聚少量的(4-苯乙烯酸合成-顺丁烯二酸)钠盐(PSSMA)加入水热系统。此外,在PSSMA和盐酸的存在下,制造了由尺寸在1.4至5.2μm之间可调的纳米球构成的球形超结构。此外,碳化的碳超结构显示出良好的性能,可作为催化加氢的载体。这些发现可能为设计越来越复杂的功能性生物质衍生材料开辟一条新途径。
