▎ 摘　　要

The tin oxide (SnO2)-graphene composite was synthesized by the in-liquid plasma method using SnO2 nanoparticles (average diameter similar to 30nm) dispersed ethanol as a precursor without providing external heat. As observed from scanning electron microscopy (SEM) and transmission electron microscopy (TEM), the SnO2 nanoparticles were distributed uniformly on flaky graphene sheets. The formation of SnO2 and high crystalline graphene was supported by the Raman analysis and x-ray diffraction (XRD) studies. A facile, low-cost method operating at atmospheric pressure based on the in-liquid plasma technology can be utilized to fabricate SnO2-graphene composite using minimum precursors for future applications such as gas sensing devices and fuel cells.
