Here, Cu-modiﬁed carbon spheres/reduced graphene In ﬁnal form 17 January 2018 oxide (Cu@CS/RGO) composite have been prepared as NO gas sensor material. Carbon sphere in the Available online 31 January 2018 interlayer of RGO can increase the speciﬁc surface area of RGO. Copper nanoparticles decorated on the surface of CS can effectively enhance the adsorption activity of RGO as supplier of free electrons. The Keywords: experimental results showed that its particular structure improved the gas sensitivity of RGO at different
