Co3S4 hollow nanospheres grown on graphene as advanced electrode materials for supercapacitors†
Abstract
A novel nanocomposite of Co3S4 hollow nanospheres grown on reduced graphene oxide (rGO) has been synthesized by a facile two-step method and used as an advanced electrode material for supercapacitors. The intriguing formation and attachment mechanism of these Co3S4 hollow nanospheres on
