Three-dimensional, superhydrophobic, reduced graphene oxide (RGO) with unique hierarchical structures is synthesized by spark plasma sintering (SPS) in one step for highly selective NO2 detection. Because the oxygenated functional groups in graphene oxide (GO) can be effectively removed to a minimal...
