Structural control of crumpled sulfur‐assisted reduced graphene oxide with elemental sulfur for supercapacitor

Crumpled graphene oxide (C-GO), a three-dimensional (3D) structured material, has many advantages that can be of value in high-performance supercapacitor electrodes. However, graphene oxide loses its morphology and advantages during the solution reduction process with polar solvents, which leads to restacking of individual sheets. In this work, we introduce an eco-friendly and simple C-GO reduction method using elemental sulfur. Since sulfur is...
