Abstract

image

Graphene oxide is effectively reduced by H2S and a graphene/sulfur hybrid is simultaneously obtained. The resulting graphene sheets interlink, forming a curly and porous structure that accompanies a uniform distribution of sulfur on the graphene sheets. The product is a promising electrode for Li-S batteries and provides a novel strategy for the removal of H2S.
