Microbubble effect-assisted electrolytic synthesis of hollow carbon spheres from CO2

Abstract

A one-step high-yield synthesis of well-developed hollow carbon spheres was achieved by an electrolytic conversion of CO2 in CaCO3-containing LiCl–KCl melt at 450 oC. Manipulating electrode potential allowed the occurrence of microbubble effect associated with the as-formed CO (intermediates of CO32– reduction) in ultrathin carbon sheets, therefore triggered the growth of hollow structures. The SEM results also reveal the good plasticity of the carbon sheets at evelvated temperatures. The micronsized hollow carbon spheres showed favorable capacitive properpties, and can be used as catalyst supports as well.
