Figure 2

(a) Scheme illustration for the formation of Sn quantum sheets confined in graphene, (b) TEM image, (c) HRTEM image, (d–f) AFM image, the corresponding height profile and scheme illustration and (g) micro-Raman spectrum of the Sn quantum sheets confined in graphene. (h) TG analysis of Sn quantum sheets confined in graphene, 15 nm Sn nanoparticles and 15 nm Sn nanoparticles mixed with graphene. The scale bars in (b–d) are 100, 10 and 200 nm, respectively. The inset circles in (c) denote the presence of Sn quantum sheets.
