Synthesis of Porous Carbon Hollow Particles from Polymer Hollow Particles

Abstract

Carbon hollow particles (CHPs) have a lot of excellent properties such as a high specific surface area, large pore volume, and the presence of nanovoids, therefore they are applied to catalyst carriers and Li-ion batteries. However, a conventional method, hard templating method, has many problems. In this study, we developed a new method to synthesis CHPs improving thermal resistance of hollow particles (HPs) made of polymer by Friedel-Crafts hyper-cross-linking and Flame resisting treatment. This method does not require any templates which need to be removed and avoids using harmful materials such as hydrofluoric acid.
