In this study, SnO2/Graphene hierarchical nanostructures had been synthesized successfully by a two-step vapor transport method. We not only explore the effects of the different growth time on the resultant structures of graphene, but also observe the morphological evolution to investigate the growth mechanism. The results show that the number of the layers of graphene increased with increasing the growth time when a mixture of methane and nitrogen with a ratio of 90:30 was introduced and the growth temperature was kept at 1000˚C. Moreover, we found that the growth mechanism of grapheme grown on the copper foil in this study is different from that grown by the low pressure chemical vapor deposition (APCVD). Here the granules of C-Cu alloy play an essential role in the growth process of Graphene. When methane is disassociated into ionization species, small graphene grain will grow on the surface of copper foil in the initial stage. The absorption of carbon atoms around the graphene grains will lead to formation of C-Cu alloy that can provide sufficient carbon atom sources for the continuous growth of graphene. For the growth of SnO2 nanowires on the graphene substrate, a thin layer of gold was deposited on the graphene substrate and SnO2 nanowires were grown by an Au-catalytic VLS growth mechanism. The structure of SnO2 nanowires is confirmed to be tetragonal rutile and the growth direction is along . For gas sensing measurements, sensors based on graphene and SnO2/Graphene hierarchical nanostructures are fabricated and their sensing properties to NO2 gas with various concentrations were measured at different operation temperatures. The results show that the SnO2/Graphene hierarchical nanostructures have higher sensitivities than graphene, which can be attributed to their high surface-to-volume ratios, and the formation of numerous Schottky barriers between SnO2 and Graphene that provides the advantage of catching electrons.
