Abstract

Morphology-controlled carbon hollow particles have been successfully prepared via carbonization of the resorcinol-formaldehyde (RF) hollow particles synthesized from O/W/O inverse-emulsion system. Various morphologies of carbon hollow particles such as hollow spheres, bowl-like structure, and capsules were tailored by adjusting the pH values of RF precursor. The obtained carbon hollow particles exhibited similar microporous properties with specific surface areas of 526-659 m² g^{- 1} and pore volumes of 0.26-0.43 cm³ g^{- 1}. Based on these results, it was proposed that the low initial pH value of RF precursor and the stability of inverse-emulsion system were crucial in fabricating morphology-controlled carbon hollow particles.
