Uniform, < 10 nm sized, hollow carbon nano-shells (HCNS) have been prepared via a single-step, thermal treatment of alkanethiol stabilised Ag nanoparticles (TS-AgNP). Direct evidence for the formation of spherical HCNS from TS-AgNP is provided by in situ MEMS heating on Si₃N₄ supports within a TEM, and ex situ thermal processing of TS-AgNP on carbon nanotube supports. A mechanism is proposed for the thermally driven, templated formation of HCNS from the TS-AgNP stabilising layer, with Ag catalysing the graphitisation of carbon in advance of thermally induced AgNP template removal. This facile processing route provides for excellent size control of the HCNS product via appropriate AgNP template selection. However, a rapid rate of heating was found to be crucial for the formation of well-defined HCNS, whilst a slow heating rate gave a much more disrupted product, comprising predominantly lacy carbon with decreased levels of graphitic ordering, reflecting a competition between the thermal transformation of the TS-layer and the rate of removal of the AgNP template.

通过链烷硫醇稳定的Ag纳米颗粒（TS-AgNP）的一步热处理，制备了尺寸小于10 nm的均匀空心碳纳米壳（HCNS）。TS-AgNP形成球形HCNS的直接证据是通过在TEM中对Si ₃ N ₄支撑体进行原位MEMS加热，然后进行非原位加热碳纳米管载体上TS-AgNP的热处理。提出了一种机制，用于由TS-AgNP稳定层进行热驱动的模板化HCNS形成，在热诱导的AgNP模板去除之前，Ag催化碳的石墨化作用。通过适当的AgNP模板选择，这种简便的加工路线可为HCNS产品提供出色的尺寸控制。然而，发现快速加热速率对于形成清晰的HCNS至关重要，而缓慢加热速率则产生了更多受破坏的产品，其中主要包括蕾丝碳，石墨有序化程度降低，反映了热之间的竞争。 TS层的转化和AgNP模板的去除率。
