Abstract: Gas sensor performance is strongly influenced by the crystal structure, composition and morphology of the material used. In this paper, structural and morphological analysis of nanocomposite SnO2-Graphene synthesized by Sol-Gel method with the composition of 1:1, 1:2, 1:3 will be described. Analysis of the morphology and structure of nanocomposite SnO2-Graphene is investigated using XRD, SEM and TEM with the purpose of obtaining the crystal structure, morphology, composition and size of the resulting particles. The XRD results showed that the formation of the crystalline phase can be recorded at 2θ = 26.64; 34.2; 51.92, where the results of SEM show that the nanomaterial SnO2 has tetragonal structure while the graphene has hexagonal structure. The nanocomposite SnO2-Graphene has nanorod pattern. Furthermore, the surface analysis using TEM of nanocomposite SnO2-Graphene shows that the surface has the rod diameter in the range of 5-8 nm. The unique nanopattern of SnO2-Graphene will have potential applicability as the sensing material for CO gas sensor.
