Spherical, twiddle and hollow hemispherical reduced graphene oxide (rGO) structures could be fabricated by tuning the GO assembly in the diffusion-controlled micro-droplets, and their size and thickness could be adjusted by controlling the concentration of GO and pH of the droplets. Besides, the porous rGO architecture was produced via wet etching of rGO-SiO2 composites, and their plasamon effect was characterized.
