Abstract

A strategy is presented to chemically bind sulfur and its discharge products with a graphene-supported N/B-rich carbon layer with various N sites and a unique N = B/N-B site in the surface carbon frameworks, prepared by polymerizing and carbonizing ionic liquids ([Emim]BF4) onto the graphene.
